So is the innovation to make something that was available in Lisps / Smalltalks, available within the different constraints of Ruby. (I should check how Smalltalk blocks behave.)

Any old math with consistent types and incorrect calculation? (If only we'd diff'd the output with some known result.) No doubt we're at cross purposes. I'm a little surprised that you haven't mentioned — "Prog

The benefits are not the same. Code can type check but not be correct. There's no free lunch. Some languages require explicit type definitions others don't.

Ummm wouldn't that be check the return value which the type checker doesn't already know?
