Does Perl need a no-op function?
With the addition of "no bare literals", it makes constructs like
1 while some_func();
an error. I propose creating a no-op function "nothing" that can be used
here or anywhere else you specifically wish to do nothing at all.
given $this {
when Even { nothing };
when Prime { ... };
default { ... };
}
As a side question, I assume that there's a predicate form of "when",
but it's not mentioned.
given $this {
nothing when Even;
when Prime { ... };
default { ... };
}
