@{pop} doesn't work as you intended, because it refers to the plain old array @pop. The parentheses in @{pop()} make it into an expression, which is evaluated.
However, you could save a character by using a plus instead, as in @{+pop}. Update: But, if you wanted to save even more characters... :) 51 characters.
