In the past I have used a regex with 'eeg' to do the evaluation in
place. However when searching for an online example of that, my example
is in the Cookbook Recipe 1.8, I found a reference to perlfaq7 that
suggests that be avoided in favor of using a hash in a similar manner to
in the other thread recently discussed here. See the "How can I use a
variable as a variable name?" in,

perldoc perlfaq7 

Specifically the part on why using 'eeg' on a regex should be avoided.
