Re: beamer columns

[Carsten Dominik <carsten.dominik@gmail.com>]

Hi Darlan,

I have gone through a number of ideas for how to create columns
during the past few days.  I also already considered and ultimately
rejected the idea to use comments or other special syntax to create
columns.  I think this would be too specialistic.  It will work in
your case, where ou use a plain list on the frame - it will not work
in someone else' case where the items on the frame are also
headline or even headlines that become special environments
like proof or block or theorem.

But thanks for chiming in, and if there are more ideas I'd like
to hear them.

- Carsten
