To be more general, some day Bison might possibly need symbol attributes 
other than semantic value and location.

I would prefer:

  a(name1): b c() d(@name2, #name2) e($name3, #name3, %name3)

That is, (name1) makes all attributes available.  If you want a specific 
subset, list the items in that subset.

Yes, we're back to the previous verbosity, but I think it's not terrible, 
I think it's better than ($#%name), and we appear to have no need for it 
any time soon anyway.
