Actually, after a bit more experimentation, I don't object to 
removing the scope on local variable delegates. Replacing those 
with a nested function declaration and a local pointer to 
function seems to work fine with no GCing, at a very slight cost 
in elegance IMO; I prefer the delegates to using '&' on a 
function. It is good to see features being removed from D.
