Since TeXmacs has already a parser for math (used for semantic checking) maybe it would be possible to extract a syntax tree (with correct precedence rules) and generate a corresponding scheme function.

The question is whether TeXmacs would really be in its role here.
This could be considered to be the job of plug-ins.

This is only part of the subject. It makes sense to have the parsing part
inside TeXmacs. What to do with it, computationally speaking, is another matter.
In fact, we already _do_ have the parsing part; this is precisely what
std-symbols.scm and std-math.scm are about. Another question is what
we could do with the parsed formulas. We might generate content MathML
in addition to presentation MathML. I don't understand why you mention LaTeX
in this context; it even does not support clean presentation markup.
Yet another issue concerns the semantics of symbols/formulas.
In different areas, the semantics may differ,
so not everybody will necessarily agree with our decisions.
Best wishes, --Joris
