I don't think it's a limitation, you can use @{cond?\@a:\@b}. but i would like to spend more words on why push is prototyped: i'll check around.

    So we don't have to pass a reference for the first argument.

    If there weren't a prototype, the array being passed in would be flattened:

    push @array, $value;

    would be equivalent to:

    push $array[0], @array[1..$#array], $value;

    Let's compare two subroutines with and without prototypes, and see what's in @_:
