(Just in case anyone is still using HTML::Embperl..)
@param is shoved into the correct package via a glob assignment (same
as other "magic variables"). These variables are marked as "imported"
by perl and HTML::Embperl::cleanup() skips them - which is mostly ok for
other variables, since they are simple scalars. @param however, could
hold all sorts of large (or important) objects until that particular
file is executed again.
I haven't tested Embperl (v2), but a quick visual check through the
relevant source sections makes me think this problem doesn't exist
there (the "importing" is done differently).
Here's a simple patch to cleanup @param at the end of Execute():
