Thanks for the report.  I will look into it. 

I believe this one started with the transition to named nodes.  
It has to do with parsing a subcircuit call, which has a 
variable number of nodes and always has a "value" which is the 
name of the .subckt to call.  Without punctuation, it takes the 
last one as the subckt to call.  The same parsing function is 
used regardless of the kind of device.

I recommend to enclose the connection list in parentheses.  The 
named parameter list ideally also should be in parentheses. 
This will avoid any confusion of which names are interpreted as 
nodes, model names, or parameters.

Check this one ....

X1 a b c d e f g h i j

What does it mean?

Obviously (?), a,b,c are nodes.  d is the model name.  e,g,i are 
model parameters.  f,h,j are parameterized values, either 
passed in or defined by .param.

X1 (a b c) d (e=f g=h i=j)
clarifies it.

It will be a good thing when we can move on, and put the spice 
format behind.  Verilog-A support really will happen.
