Instead of using Embperl::OUT etc. directly, make an alias into your
package. You can make this alias to HTML::Embperl or Embperl, depending from
where you are called, e.g.:
*OUT = \*Embperl::OUT ;
*fdat = \%Embperl::fdat ;
or if you want to have compatibility, you can create the alias in
HTML::Embperl namespace:
*HTML::Embperl::OUT = \*Embperl::OUT ;
*HTML::Embperl::fdat = \%Embperl::fdat ;
but this will not work if you use 1.3 and 2.0b6+ on the same Apache server.

If only one module of both is loaded, you can simply test for existens for
some symbol you now that should exist e.g.
if (define(&Embperl::handler))
.....
if both are used in the same server that won't work, and you have to walk up
your call stack using the caller function, to see from where you are called

That's fine, but how do I tell which one called me? The joys of
object-oriented programming--my module is two deep down to easily be
passed the information.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
