I would have to list this as my #1 complaint about erlang.  Far above 
any other gripes.
I realize the tracing facility is robust.  But it is certainly not 
convenient. Especially for someone new to erlang.
I don't understand why the debug compile can't provide this info by 
default.  Can someone explain what it would take to put this into a very 
near future release?
