Because this is not a bug. As Javier already pointed out, dynamic
languages use lots of heuristics to optimize its execution. It is
always possible to handpick some special case that breaks those
heuristics and produce bad behavior.
The heuristics are all driven by *real* code, not code specifically
written to break them. (Otherwise there will always be "bugs".)
We already have several real cases of people that have real problems.
Please let us dedicate our time to them.
