96    This will require duplication of the continuation of the conditional (but we should only

109    Better handling of variables that determines the scope of a variable based on its actual use,
110    instead of where the user defined it.  So, for example, we should lift strand-invariant variables
111    to global scope.  Also prune out useless variables, which should include field variables after the
112    translation to mid-il.
