Why do you expect "new"?

There is a conflict here between the preserving variables in the  
body, or the variable in the hoist.

We could potentially allow the programmer to disambiguate: do not  
hoist by default, but allow it to be specified explcitly, by  
exporting "this".

     # For example
     i. =
         i = 0
         incr() =
             j = $(add $i, 1)
             i = $j
             export this i # export the "i" field, but not "j"
                           # then export ("hoist") the object

     i.incr()
     println($(i.i)) # prints "1"
