...Right, but it's an extra I/O op (or more) just to pull in the sub out of the .al file, each on an individual basis...

Are the savings worth the cost?

$ perl -MMIME::Base64 -e 'print decode_base64 "YWNlQHRvbW15YnV0bGVyLm1lCg=="'

    Presumably that will depend on the individual script's use case.

    If only 1 of every 1000 runs will perform the conditional require, then it's probably negligible. If 999 of every 1000 runs needs it, then it is probably not negligible.

    If in doubt, benchmark!
