prefer_ generic_ function_ type_ aliases
Prefer generic function type aliases.
Details
#PREFER generic function type aliases.
With the introduction of generic functions, function type aliases
(typedef void F()
) couldn't express all of the possible kinds of
parameterization that users might want to express. Generic function type aliases
(typedef F = void Function()
) fixed that issue.
For consistency and readability reasons, it's better to only use one syntax and thus prefer generic function type aliases.
BAD:
typedef void F();
GOOD:
typedef F = void Function();
