I wrote a bug about a "leaky abstraction" optimization messing up coverage testing 2.5 years ago, and it was closed as won't fix: http://bugs.python.org/issue2506. The debate there centered around, "but that line isn't executed, because it's been optimized away." It's common in sophisticated compilers (as in, any C compiler) to be able to choose whether you want optimizations for speed, or disabling optimizations for debugging and reasoning about the code. Python would benefit from the same choice."Aggressive" optimizations can be enabled with explicit options, in order to leave normal "debugger-prone" code.
