[erlang-questions] gen behaviors and global groups

[Serge Aleynikov]

You are right - both gen_{fsm,server} have enter_loop/5 and 
get_proc_name/1 that require very similar patching.  Though the original 
question still stands.  I take a guess that perhaps global groups where 
introduced later, and the implementation of gen behaviors wasn't brought 
up to speed to include this feature.  If that's the case, perhaps the 
implementation can be safely adjusted as it shouldn't break any legacy 
code, yet be quite useful for large deployments.
