Update: The required sub-scripts should have failed to compile under strict. If you're using do instead of require, you should check $@ and $!.

Remember, I wasn't using strict in the sub-files before. I had assumed that when I said "use strict;" in the main file, and then was bringing in the other subroutines via "require subfile.pl;" that the "strict" had applied to the entire global context. Remember, the global variables are all correctly shared among the files--so why wouldn't strict be shared, too?

In any case, I had no issues compiling until I added "strict" to the sub-file.

I'm not using "do" anywhere in the entire script at this point.
