The difference between bytes and str wasn't the main thing that killed
Py3k adoption. It was ONE thing, but it was one thing that could have
been managed in and of itself. The problem was that they tried to
FORCE the Unicode migration down everyone's throats and in doing so
shattered compatibility (and then they also decided to break
everything at once on the theory that you'd have to port your code
anyway, which made the porting effort that much harder). Lua could
easily avoid that problem by maintaining a focus on compatibility.
