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.š

But˛ 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

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

˛) as already said

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
