[Bug 872503] Re: Pyflakes is unable to recognize string substitution as a use
Pyflakes' goal is to be useful. It does not try to fit into any
particular formal mathematical framework.
Personally, I avoid the question of what pyflakes should do in this case
by not using locals() to interpolate into strings. I don't find that
this constrains my ability to write programs easily.
I would say that injecting `locals` into a scope and expecting Pyflakes
to behave correctly in that case is more unreasonable than expecting
locals() interpolated into a string literal to mark the keys in the
string literal as used locals. So, go ahead and submit a branch
implementing this feature.

Title:
Pyflakes is unable to recognize string substitution as a use
Status in Pyflakes:
New
Bug description:
See attached program for a trivial example of a common idiom:
"my special string %(with_a_variable)s"%locals()
I wouldn't expect pyflakes to know how to deal with an arbitrary
dictionary in the right hand position, but the use of locals() means
that certain variables are actually used!
