> We see that languages like Perl and Python have huge numbers of libraries for doing all sorts of tasks. Those libraries are only accessible through the programming language they were developed for. This is a missed opportunity for the languages to interoperate synergistically with the rest of the Unix ecosystem.

What would this interoperability look like, in practical terms?

For example, how would you invoke a program in language A from language B, other than the typical existing `system.exec(...)'.
