removal of translator hack

[Eric Dean Tribble <tribble>]

sounds good!  So far I've avoided modifying the parse node classes
specifically for the translator.  Your changes start along a path that
is cleaner for lots of things:  make a prse-tree, then transform the
parsetree, then print the result.  TypeDescription objects also lean
in this direction.  They really ought to be a different type of
ParseNode.

good stuff
