You could just store the AST in your fake method, put the halt as an
annotation, then
interpret the AST with a special interpreter that checks for the annotation.
Phillippe did a evaluation-visitor for the RB AST, and the RB AST allows for
properties to be set on any node. The code is in the Reflectivity package (part
of the Persephone "JIT"), so we would have already large parts of the needed
infrastructure.
