This is, perhaps, a silly question, but it's something that I've wondered about: is it possible to, say, define a Ruby/Python/Perl/etc. function in some file and then source it in Bash (to make it available anywhere in the current shell)?

At the moment, I "source" scripts/functions in other languages by creating a bash alias that executes that script... But I wonder if it's possible for Bash to interpret those other functions directly?

Thanks. :)
