Alternatively, why not fix Karthik's stated problem with some analogue
to `org-insert-structure-template'? E.g. `org-insert-latex-environment'.
It would insert a latex environment, after prompting for the name, or
update the environment name if called with a region that started with
\begin{FOO} and ended with \end{FOO}.
