I care less about the name than the functionality, could be also "count" or whatever suits.

I suppose "elems" is already known from ruby or perl6? So why not.¹

But² tobyinks and your suggestion w/o prototypes is considerably slower on large arrays.

DB<106> use Time::HiRes qw(time) DB<107> sub elems { scalar @_ } DB<108> @a=(1..1e6);0 DB<109> $t=time; $count = scalar @a; print time-$t 7.10487365722656e-05 DB<110> $t=time; $count = elems @a; print time-$t 0.0554749965667725

Perl 5.10!

Cheers Rolf

¹) Well the plural in "elems" somehow indicates a list to be returned.

²) as already said


In reply to Re^2: new keyword "size" to avoid scalar trap ? ( scalar @array != scalar(LIST) ) by LanX
