New submission from Gil Forcada <gil.gn...@gmail.com>:
Given the following code:
class MyClass(object):
@property
def my_function(self): pass
Parsing it with ast module, the lineno and col_offset of the ast.FunctionDef is
reported to be where the decorator starts (i.e. line 3 column 4) rather than
where the actual def statement is (i.e. line 4 column 4).
This is due to the decorator that is part of the ast.FunctionDef, but as there
can be multiple decorators (which they don't provide their own lineno and
col_offset arguments) and they can span across multiple lines, there is no
reliable way to actually know where the actual def statement starts physically.
See this bug report on flake8-builtins plugin (I'm the author) reported by
@dhood user on github:
