Re: [sv-bc] Function in generate block

Rakesh,

This entire area is defined very, very poorly in 1364-2001.
There are all sorts of issues with the spec as written in
1364-2001.  I generally agree with your view in this specific
case, but I would strongly recommend that people not try to
conform to the 2001 spec as written but rather actively
encourage moving to the 2005 spec since naming issues are
well defined.

Gord.
