Problem: You are given the input string "88-99", and you need to output each number from 88 to 99, inclusive.

$ perl -E'my ($lower, $upper) = split(/-/, pop); say for $lower .. $up
+per' 88-99
88
89
90
91
92
93
94
95
96
97
98
99

The key here is the range (..) operator. From perldoc, the range operator returns a list of values counting (up by ones) from the left value to the right value.
