Serhiy Storchaka <[email protected]> added the comment:
The most common error is missing keyword "await" in function call. "f()"
instead of "await f()".
There is a way to detect this error at runtime with minimal false positive and
with minimal overhead. We can add a new opcode which checks if the value on the
top of the stack is awaitable and raise warning/error in that case, and add it
after every functional call whose result is ignored in asynchronous functions.
It could even be merged with POP_TOP to reduce overhead.
CALL_FUNCTION ...
WARN_IF_AWAITABLE_AND_POP_TOP
