Subject: alternatives to ? : contruct

As an alternative to:

a = y == z ? b : c 

we can say:

a = (b if y == x) || c

Can anyone think of others?

I'd really like to be able to say:

a = b if y==z otherwise c

but the precedence of _or_ is not low enough for this to work. Would
changing the precedence of _or_ to be lower than expression modifiers
brake much? I believe _or_ is presently just above the expression
modifiers today. Then again perhaps that would be confusing. Perhaps
an _otherwise_ operator would do the trick.

This is trivial really, but ruby specializes in niceties which many
might deem trivial but which all add up to an amazingly productive
environment.
