I'm meditating if Perl should introduce an explicit keyword size (or count ¹) always return the number of elements of lists and arrays... (length is already taken and scalar is to overloaden)

so

size @a := scalar @a;
[download]

and

size (a..c) := scalar @{[a..c]}
[download]

I know "explicit is better than implicit" is more a Python dogma, but since even popes still fall into the scalar trap we should maybe consider "another way to do it" (best Perl tradition =).

PS: I tried to provide an example implementation of size, something like

sub size([@$];@) {
...
}
[download]

but was to lazy to fiddle around with prototypes.

Anyway IMHO a reliable implementation will need more parsing magic than prototypes can bring to avoid disambiguation.

¹) or whatever
