Yes.  Does that sound reasonable to you?

If we're going to give the default a name, why have a default at all?  
Imagine reading a grammar file containing the following two directives:

  %code { CODE }

  %code "methods" { CODE }

They look different, so my intuition says they should do something 
different, but you're proposing that they do the same thing.

Why do you want to do this?
