A robust version of overlay commands?
Currently, all beamer overlay commands seem to be fragile. This is most obvious and annoying with
\emph in sections.
passes (see example file).
While there is a workaround (
\protect'ing), I think this is still unfavourable and most probably very irritating to new users (it is also not documented).
I don't know if it is possible to make those commands robust in general or provide a
\DeclareRobustCommand alternative with overlay spec (my attempts all failed), but it would be very welcome.
