tests: Add test for semantics of for-loop that optimisation can break. 2014-12-12 01:40:41 +08:00			`# test assigning to iterator within the loop`

py: Fix optimised for-loop compiler so it follows proper semantics. You can now assign to the range end variable and the for-loop still works correctly. This fully addresses issue #565. Also fixed a bug with the stack not being fully popped when breaking out of an optimised for-loop (and it's actually impossible to write a test for this case!). 2014-12-13 01:19:56 +08:00			`n = 2`
