Inverse of 'chop @array'

[gusmeister]

'chop @array' removes the last character for each element in an array. If I
want to do the inverse and append a character to each element, how would I
do that (without using a 'foreach' loop)?

You could use map instead, but that would just hide the loop inside of it's
own logic.
