  This is a good point (which I already mentioned): It is in fact not very
difficult to insert those extensions \tex/ by hand with a good editor. But
this concerns new code.

  My idea is though different from a compatibility mode, because the idea
is that one should be able to write {say)
  \module{code}{tex}
    ... % TeX definitions
  \module{endcode}{tex}
and then the TeX definitions expand to names \tex/<command name>.

  So this TeX code can then be used as module code, used together with
other modules without code clashing. In a compatibility mode, one is stuck
with TeX for the rest of the compile. Here the idea is that after
\module{endcode}{tex}, the TeX names \hbox etc do not any longer exist; all
definitions are of the form \tex/hbox, etc.

  I am not sure if it can be done like this and work correctly, but that is
what the idea is.
