Not trying to argue, just curious: what about Ruby you find surprising?

Off the top of my head (there is more):

* Floats are printed without rounding

* You can write x = foo unless foo but not x = foo if ! foo

Floats are printed without rounding

Isn't that a good thing? I like knowing the real value I'm passing around. It does round...eventually (at 14 decimal places or so).

You can write x = foo unless foo but not x = foo if ! foo

This is incorrect.

I could have sworn I tried that a week ago and it didn't work. Thanks for the correction.
