Provide support for languages other than MUF

[tanabi]

Python, lua, or other languages could be considered to modernize us past the clunkiness of MUF.

If MUF were more like Standard Forth (with the ability to define source-parsing words and so on), you could theoretically define other (non-statically typed) languages as MUF libraries, and declare the language to use just by $includeing the right one. (This also requires a library's functions to be available directly at compile time, not just through libref funcname CALL.)

However, even the first part of that (making MUF more like Standard Forth) would probably be a significant ordeal, and writing a language library would be herculean.

We can look at this if we want to use Python.

Seems worth exploring.
