Yes. The EXPR domain is *not nice*

Could you elaborate a bit on what you mean by analysing an Expression? I.e.,
could you please provide an example.

I reached the conclusion that the EXPR domain badly needs an update. However,
for the time being ...

On the other hand, "parsing" an expression is quite certainly *not* the way you
should do things with axiom.

Still, more often than not, EXPR is wrong and you are right...
