What does Identifier refer to here in your rewrite? It is just the last
variable that is parsed. When you are looking in Works, you are probably
looking at the parse tree and not the AST. Why are you trying to rewrite the
first token to an Imaginary?
What you want is:
: id+=Identifier (',' id+=Identifier)*
->^(VarDecl {$varType} $id)+
Then reflect that in your tree parser. I have never quite seen the reason
behind eliding the fact that multiple declarations were made on the same
type, but if that is what you want, then you need to do it as above.
