What about the dot-parser?  The one that wraps a method in >o <method> o>?

: >oo> ( xt -- )  postpone >o compile, postpone o> ;
:noname ( object xt -- )  swap >o execute o> ; \ interpreter
' >oo>                                         \ compiler
:noname ( xt -- )  lit, postpone >oo> ;        \ postponer
recognizer: r:moof2

You still can do that with an action, but at a performance cost.

The TO-recognizer wants to work with locals.  I suppose that

: foo { a b c }  ... ->a  ... ->b ;
: bar { b a }  ->b ... ->a ;

will address the corresponding locals of foo and bar.  The compilation of 
those would be something like

: ->a laddr# 0 ! ;

and then only work when a is the first local.
