Well, I would rather keep the formatting in the org file, so no
\structure in the template.  But otherwise your suggestion seems exactly
what I need :).

I was thinking the same.  That's why I felt the need for the old
BEAMER_arg property!

This might be nice, but as you say could be overkill.  Although, there
are a few other cases which is harder to use with the current syntax.
Take minipage as an example, it takes 3 optional arguments[1].
Presently there is no way of dealing with something like that.  Removing
the autowrapping of brackets would allow such cases, but it would
probably break a few Org files in the wild.  From that perspective, a
lambda might be the way to go.

Nice idea.  I have never really explored using blocks (other than for
raw latex), maybe I should ...

Thanks,
