My opinion about the \begin<env>=E2=80=93\end<env>: I don=E2=80=99t like =
it at all.
ConTeXt uses \startenv =E2=80=93 \endenv, which is a bit better. A perfec=
t thing
would be: \envstart =E2=80=93 \envend. Reason: autocompletion works much =
better.
Now I always have to type \begin{do <tab> to get \begin{document} as
completion. With \documentstart it would only be \do <tab>. I don=E2=80=99=
t know
if anybody here likes this, but Joseph asked for discussions=E2=80=A6

Cheers
Arno
