Lots of good answers so far about using arrays, hashes etc, so
won't bother going there... look below to see an OOP that works
efficiently, using NAMEs rather than refs.

This is called a soft reference, and soft references are generally a bad
idea. However, it should work.

You're going about it the wrong way. I assume that based on some previous
criteria, you need to perform a certain action, and you have that criteria
stored in the array: @list_of_subs
See if this works for you.
Create 1 sub, which we'll call MySub.
