Yeah to be clear I meant performance-wise. In terms of development speed it looks like it just goes to insane extreme on the "fast at the beginning / fast in the middle" trade-off. You know how dynamic typing can be faster to develop when you're writing a one-man 100 line script, but once you get beyond that the extra effort to add static types means you overtake dynamic typing.

Performance-wise I'll admit I don't really know. But I do know that performance is at least decent, in that it lets you experiment easily with pretty much any array problem. Your dynamic/static typing analogy is pretty much on point.
