Hi at the ruby team,
I'd like to suggest to enhance
Numeric to provide two new class methods, which shall be:
Integer.zeroshall be equal to
Float.zeroshall be equal to
BigDecimal.zeroshall be equal to
Complex.zeroshall be equal to
one, you get the idea.
Numeric already provides
Numeric.zero.zero? shall always be
I expect this to make code more explicit. And it would save a pair of braces.
(Don't laugh--This really got me here.)
Maybe you already considered that for 3.0, which would be a late addition.
Ruby shines in teaching mathematics. You know, we have zero and one there.
I use ruby in the financial realm. For me, it's important to write
I expect that the new API should not break existing code. We could try it with Rails first. Let's ask them.
It would be nice to have that in [Rails] 3.

Do these methods work for you? They need no braces.
