Ok, the problem is this - plenty of code, many times called, probability of
raising exception is about 1e-5.
From many reasons is not possible to serialize params into string just
for the case that exception would be raised.
Is there possible to save *values* of params *generically* just from the exception
raised?
Please no reflection based attempts - it is *not* possible - only debugging API can
do the trick, but how ???
Thanks for any ideas!
