Re^3: new keyword "size" to avoid scalar trap ? ( scalar @array != scalar(LIST) )

in thread new keyword "size" to avoid scalar trap ? ( scalar @array != scalar(LIST) )

It is most probably the copying of the argument list (the full array) in the function call that takes this time difference.

Passing a reference to the array would probably solve the issue, but the syntax would become less obvious to use.

No copying takes place :) however the same amount of scalars is aliased ;)

Thats why we need prototypes or a special C-implementaton.

according to the perlsub sub size (+;@) { } could be used, to call

 size @array

or

 size 1,2,3

but since I'm using 5.10, I can't test it...
