Ok, got it, thanks for the reference.

Moreover, replacing `TeX-in-commented-line' with `TeX-in-comment'
inside `LaTeX-current-environment' makes it a recursive function.  In
some situations I get
  Debugger entered--Lisp error: (error "Lisp nesting exceeds
`max-lisp-eval-depth'")
So probably using `TeX-in-comment' isn't a good idea at all.

How about not checking comments in `LaTeX-current-environment'?  I.e.,
something like
--8<---------------cut here---------------start------------->8---
  (setq arg (if arg (if (< arg 1) 1 arg) 1))
  (save-excursion
    (while (and (/= arg 0)
        (re-search-backward
         "\\\\\\(begin\\|end\\) *{ *\\([A-Za-z*]+\\) *}" nil t))
      (setq arg (if (string= (match-string 1) "end") (1+ arg) (1- arg)))))
  (if (/= arg 0)
      "document"
    (match-string-no-properties 2))
--8<---------------cut here---------------end--------------->8---
This has definitely side effects, but also make it possible to put a
dummy \begin{} or \end{} inside comment to help AUCTeX guess current
environment, much like (info "(auctex) Known problems").

Do you have other ideas?

Bye,
Mosè
