Re: Secret new routine_id() feature. (Attn: Rob)

This is very interesting. Whether or not Rob decides to keep this
feature, er.. bug, I'll keep it in EG. Although, the reason you can
not call routines (by forward reference) directly is because the
parser does not see the routine as a defined symbol before it is
defined (obviously), where as routine_id() returns an id at run time.
This 'bug' also applies to variable_id() in EG, as well as
routine_name(), routine_list(), variable_name() and variable_list() as
well as read() and write().
