We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
This didn't actually catch what it's supposed to, which is cases of:
```python
for x in dict.keys():
y = dict[x]
```
But it did catch one unnecessary use of keys(), and one case where we
were doing something in an inefficient way. I've rewritten:
```python
if name.value in [x.value for x in self.kwargs.keys() if isinstance(x, IdNode)]:
```
as
``python
if any((isinstance(x, IdNode) and name.value == x.value) for x in self.kwargs):
```
Which avoids doing two iterations, one to build the list, and a
second to do a search for name.value in said list, which does a single
short circuiting walk, as any returns as soon as one check returns True.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
The arithmetic operators are now split into two groups:
* The add/sub group: +, -
* The mul/div group: *, /, %
All operators within the same group are left-associative and have equal
precedence. The mul/div group has a higher precedence than the add/sub
group, as one would expect.
Previously every operator had a different precedence and was
right-associative, which resulted in surprising behavior.
This is a potentially breaking change for projects that relied on the
old incorrect behavior.
Fixes#6870
This also fixes that the keys in ArgumentNode.kwargs are
all of the type BaseNode now. Before this commit, it was
possible that both strings and Nodes where used as keys.
Fixes PR #6166 and more specifically commit 4e460f04f3 that tried to
make sure the type of a key variable is a string but checked the type of
the value instead. Extends test common/228's limited coverage,
its only test case had (surprise) a string value. Also avoid reserved
python keyword 'dict' and potentially confusing string 'key'.
Implements #5231 for real.
* docs: document unrecognized escape sequence behaviour [skip ci]
Document that unrecognized escape sequence behaviour is like python, not
C.
* Don't try to decode invalid hex escape sequences
Don't try to decode escape sequences which should contain a sequence of
hex digits, but don't, throwing a python exception. These will treated
literally instead.
* Extend test case to cover invalid escape sequences
* tests: extend ternary test to cover bugs
See issues #5003, #3690, and #2404
* mparser: store subdir in ternary node
Ternaries don't really need subdirs, but they can be passed into
functions that expect the type they're provided to have a
subdir. Provide it to fulful the interface.

The documentation states: "In other cases you can get multi-line
statements by ending the line with a \." but that seems to never have
worked.
Closes: #4720
Simplify support for alternate bases using int(..., base=0) which
auto-detects it using the standard Python syntax for numbers.
Octal numbers are useful to specify permission bits and umasks.
Binary numbers are not super useful... But considering we get them for
free, let's allow them here too.
v2: Tweak the regex so it doesn't accept a decimal number with a leading
zero, which is invalid for int(..., base=0) and would raise a ValueError
if passed around.
For now dicts are immutable, and do not expose any methods,
they however support "native" syntax such as [] lookup,
and foreach iterating, and can be printed.
Examples:
meson.build:2:0: ERROR: Dependency is both required and not-found
meson.build:4: WARNING: Keyword argument "link_with" defined multiple times.
These are already matched by the default compilation-error-regexp-alist in
emacs.
