I agree that it is a great time saver while developing. I wouldn't use it
on a production machine because it implements a similar hack to the one
I described in a prior message. It adds cpu time to each and every
request, and while the code seems reasonable enough, I am hesitant to
add unnecessary logic to a production system, especially a heavily
loaded one.
Apache::Reload doesn't use Yitzchak's advice of deleting the namespace
prior to reloading the module; it is assumed that the compilation of the
newer module will overwrite everything in the same namespace.
A similar module that is interesting for devel environments, but I would
not run on production is Apache::PerlVINC. This lets one use two
different versions of a module within one running instance of
apache/mod_perl.
Have fun,
-C.
