I am relatively new to Perl -- I figure there must already be a way to do this without writing my own custom subroutine. Here's my question: How can I force a scalar variable to be re-interpolated? For example, lets say that this line of code: print $raw; returns: fred has $color eyes What I want to be able to do is later set $color to equal "blue."
