[issue33521] Add 1.32x faster C implementation of asyncio.isfuture().

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

I disagree with your rationale. At least, it is not how we decide to
optimize something or not in Python. Python is first made of people who
will have to maintain the code for the next 5 years if not longer. C code
is harder to maintain than Python code.

A significant speedup on a microbenchmark is nice, but asyncio still lacks
a more general benchmark suite...

I have no opinion on this specific optimisation.
