Can anyone point me at an explanation of why this (parentheses around
variable names in prototypes) is even allowed? I assume that the proximal
cause is "Because the standard says so", but does it actually buy us anything
in terms of what can be expressed that otherwise couldn't?
Standards compliance and all that, but maybe in std=gnu++ mode we could make
it an error, or perhaps deprecated?
