Hello all,
I was developing a script using an asyncio-based API, when I came across
the need to define an asynchronous lambda.
Not really.
I found this syntax does not
currently exist. Obviously I could have (and did) just write a regular
coroutine, but for simple one-line functions and such, I think an
asynchronous lambda syntax would be useful. I do not have the experience
to write a PEP or implement this, so I was wondering what you all think
of the idea.
What I was thinking:
foo = async lambda a, b: b + await bar(a
PEP8 intentionally and properly discourages 'name = lambda ...' as
inferior to 'def name(...'. For the above,
async def foo(a, b): return b + await bar(a)
I posted an issue <https://bugs.python.org/issue33447> on the issue
tracker suggesting this, and was directed to this mailing list.
