I think you have this one backwards. This is one giant, ambiguous
global variable whose value and meaning changes constantly from
statement to statement. Think $_ but worse. You have to constantly
worry about adding in a new statement for fear it will alter the
meaning of $IT and break code below you.

This is better solved by using smaller scopes/subroutines and
meaningful variable names.
