However, this parses correctly and does what you expect.  I suggest that it 
might want to be written up as either a FAQ entry or as a documentation 
thingamawhatzis.  Watch out for the returning-locals-from-a-macro bug, though:

#macro Foo( Bar )
  #declare X = Bar(Y);
#end

#declare Y=1;
#declare Baz=function(n){n+2}

Foo(function(n){Baz(n)})

#debug str(X,5,5)
#debug "\n"
