[MLton-devel] implementing raise and the exception stack

[Henry Cejtin]

My impression is that in C++ the fancy stack-walking makes exceptions very
expensive.  One thing that I vaguely recall is some kind of trick so that
different ranges of the program counter in some way.
The slowness of handing doesn't matter much to C++ or Java since exceptions
really do tend to be some kind of error or rare event.  It would matter more
for ML.  Still, it would be interesting to play around.
