Don't get too excited.  Speedups and slowdowns in
the order of 1% are usually random cache effects
having to do with common portions of the VM main
loop having a cache line conflict; I've seen a
case where adding an *unreachable* printf() call
predictably changed the pystone speed by 1%.

Then why do I see all signal names in your list?
And all exception names?

But the string is still more helpful in the code
than the symbol name.

Sorry, but none of this changes my position;
you'll hve to find another champion.
