Hop, skip, and jumping around... I'm taking another look at Oz, a "multiparadigm" language I took a brief look at a few years ago. Along with the book "Concepts, Techniques, and Models of Computer Programming" my first look was brief and did not I did not appreciate everything about them.
I was originally put off by the shear number of capabilities in the language and presented in the book. On the other hand those capabilities fit together very well now that I am actually working through them.
OK, so the only real oddity is this: unary minus is represented as a tilde. And so...
Should not read as "about ten" but rather "negative ten". This is the same as
0 - 10
using the Oz binary substraction operator, but
-10 is invalid in Oz. I guess if that's the oddist thing...
