[Texmacs-dev] Experimental (and possibly outdated) style rewriting code

[jingkaimori]

A bunch of code evaluating style is found in texmacs.This evaluator
locates at src/Style directory in github repo, differs from current
one in src/Typeset. Defining an EXPERIMENTAL environmental variable
during building can enable these codes. However, this part seems to be
unmaintained and throws several errors, such as the symbol arg_type is
missing. After some tweaking, I managed to make this part work, and it
turned out to be able to render some simple documents. But local
documents cannot be loaded by this evaluator.

Could someone tell me how to deal with this part? This part can be
found here:  https://github.com/texmacs/texmacs/tree/master/src/Style/Evaluate
