MSL did not start out as a fully featured programming language.

Rather than extending it until it becomes one, I think a better approach would be to take
one of the existing extensible scripting language libraries and extend it with midas functions.

For example, LUA (https://www.lua.org/about.html) seems to be popular.

There were also requests for a midas extension for PYTHON (actually this has been done before,
but never added to the midas repository. I still have that code and I suppose it could be resurrected).

K.O.
