i don't have this problem as the function is generated
at runtime anyway, thusly one of the parameters to the
code generator is the type itself. an exception mechanism 
is used if / when the type of a local changes, these can
result in regeneration of the executing code, and the 
dispatcher takes care of jumping into the newly generated
code.

i hope you succeed :)
easy + fast is good :)
