:D

"Aggressive" optimizations can be enabled with explicit options, in order to leave normal "debugger-prone" code.

If you use print statements for the bulk of your debugging (many people do), unrolling loops doesn't affect your debugging ability.

Skip

It's a common practice. Also IDEs helps a lot, and advanced interactive shells too (such as DreamPie).
