Comment (by Jacob Walls):
Good question. Sorry, I wasn't trying to hide details, I just needed to
recall what I benched. I benched the case where the annotations are
available (e.g. not guarded under `TYPE_CHECKING`, which is IMO more
likely):
{{{#!py
In [13]: class Imported:
...: ...
...:
In [14]: def foo(a: Imported, b: Imported, c: Imported): ...
In [15]: %timeit signature(foo, annotation_format=Format.FORWARDREF)
4.52 μs ± 177 ns per loop (mean ± std. dev. of 7 runs, 100,000 loops each)
In [16]: %timeit signature(foo, annotation_format=Format.STRING)
7.59 μs ± 37.3 ns per loop (mean ± std. dev. of 7 runs, 100,000 loops
each)
}}}
