[Python-Dev] about line numbers

[Guido van Rossum]

Earlier, you argued that this is "not an optimization," but rather
avoiding redundancy.  I should have responded right then that I
disagree, or at least I'm lukewarm about your patch.  Either you're
not using -O, and then you don't care much about this; or you care,
and then you should be using -O.

Rather than encrusting the code with more and more ad-hoc micro
optimizations, I'd prefer to have someone look into Tim's suggestion
of supporting more efficient breakpoints...
