Hello internals,
Ondřej Mirtes (author of PHPStan) remarked to me in August that Closure is not a subtype of
callable.
The implementation of this is quite straight forward and can be seen on GitHub. [1]
The question is if there are any concern or not and if this requires an RFC or can just be merged as
is.
Best regards,
Gina P. Banyard
