But this would really be worth adding to lilypond. I am thinking
of something similar to the call of TeX or LaTeX in metapost:

  btex $c^2=a^2+b^2$ etex

or as a string

  tex("$c^2=a^2+b^2$")

That way, you could easily add paragraphs formated with TeX in various places,
you could have all the symbols you want, and especially reach better
homogeneity between the text and the score. One of the most serious
current problem seems to be the discrepancy between the text font
in a LaTeX file and the lyrics font in a score. Perhaps it can be made
identical in some cases, but it is not automatic, and the different
font families hurt the eyes.
