[Python] failing polygonal test.

[frabbit]

Python compares ints between 0 and 256 with "is" instead of "==", this causes a problem with the polygonal lib where at runtime 0.0 is compared against 0. The problematic function is Random.rand() in polygonal-core and looks like this:

inline public static function rand():Int
{
    return cast (frand() * Limits.INT32_MAX);
}

this code is called in the unit tests:

and

https://github.com/Simn/ds/blob/master/test/TestBST.hx#L252

and ends up in this compare function

https://github.com/Simn/ds/blob/master/test/TestBST.hx#L392

called by BST.find

https://github.com/Simn/ds/blob/master/src/de/polygonal/ds/BST.hx#L148

and ends up in a failing comparison here:

I guess we should disable our optimization for now and look into it again later?

Well, this issue is technically resolved, so let's close it. We can reopen it if we come across it again while optimizing.
