[Help-gnucap] named nodes

=====================
   
I just tried out both the 0.34 release and the latest 
(gnucap-2006-05-06.tar.gz)
built fresh from source. It seems that named nodes don't work 
correctly in either. 

Here's the input:

.option namednodes

Vin x 0 1 ac 1
rin x 2 1k
cin 2 0 1p

.op
.print op x v{x} v(x) v(2)
.end

------------------
0.34 gives:

and the latest build gives this:

Am I using named nodes incorrectly? Is this a bug?
Is this something I could try to fix in the source? Named nodes
would be a huge convenience. (The alternative would be to
have a preprocessor that does a string-replacement on the input
and undoes it on the output. Big pain.)

Also, is there support for libraries, of the sort Dan mentioned
on Wed, 18 Jan 2006 21:53:17 -0500 on Gnucap-devel?
Foundries generally give a set of binned models of devices 
rather
than a single model, and library support would make it feasible
to at least compare gnucap to Spice (or in my case, Spectre.)
