precisely.  formulas are visual shortcuts that are eventually handled
as _objects_, their semantics is thus simultaneously complex and
integrated. What is magic with tex coding is that it's sufficiently
generic to carry both aspects at once, in my opinion it is the reason
of the success of tex as a format used by the mathematicians
themselves, rather than only as a sophisticate software used only by
printers, what it could have been. I too do think that i requires
little effort to code maths in tex at a higher level making the coding
usable by others than experienced users (by programs, e.g.), but i'm
still waiting to see some standard coming. I wondered if MathMl would
impulse this in latex as somehow SGML/HTML did it for text, of if
anarchy would prevail...

yes yes yes ! tex (as a program) is not always coherent with tex (as a
coding scheme) though... {,} making the comma mathord (there should be
at least 2 commas in maths, one mathpunct, one mathord); in
\Sum_{i^n, {i is _not_ an index nor n an exponant,
mathematically speaking. My feeling is that the Knuthian macros play
like a virtuose with tex's font oddities and abilities, at the expense
of the genericity of the markup (too much clerveness, too many special
cases are not good for genericity...).

I know, that's how i discovered this list ;-)

yes yes (again) but this time ET98 is coupled with a week on
electronic publishing (RIDT, EP) so maybe people will be there? I'll
try to get some info about this.

i like oblique strategies ;-)
