[IronPython] Arrays in IronPython

[Martin Maly]

Array[int][int] is equivalent to Array[int]. Using this syntax, the type that takes effect is actually the type in the right-most brackets. For example:

Array[int][str] is equivalent to Array[str]

This is probably an unintentional (and admittedly confusing) behavior that we will look at fixing in the future releases.

Thanks Dino.  That's cleared up Python jagged arrays for me.

Any idea what the "Array[int][int]" means?  Iron Python is ok with it, but I
can't figure out what it is (or how to initialize it).
