I stumbled into this one today on Perl 5.22.1. The issue with this defect is 'b postpone' is the only way I'm aware of setting a breakpoint before a required module is loaded (in the case of code which uses runtime loading of module via Module::Load::load()). Anyone have any workarounds?

update: the quickest workaround really isn't one, but it works - if one can continue to just after where the module(s) are loaded, then one can set a normal breakpoint. I'm still going to have engineers who whine about having to enter one more command though until this gets fixed and backported to 5.22. :-/
