I am aware of 3 different kinds of approaches:
- writing programs in different languages, with one programming
language occupying a whole process (so, web services as you say, or
scripts, or an org-mode file, for instance);
- extending a "managed" programming language with C or C++ code; in
theory it could be possible to do the same for two different
programming languages and link both C interfaces together; this is what
SWIG (http://swig.org/) does, but using some language in another
language that way feels a lot like coding in C;
- using a common virtual machine as the target for the compilation of
many different languages (like elisp and scheme for guile).
