I can't do this since there will be multiple rules with the same 
name that require different treatment. The reason I want to use 
semantic actions is that I don't want to push an already heavy 
grammar into double or triple size just to name specific rules in 
a certain way. Semantic actions take up very little space and fit 
nicely into the syntax.


or do it with a template, holding function names as aliases:

alias actor = dispatcher!(foo, bar, baz);

I have no idea what you mean. :D
