x1:

Yes, you can do that.

asdf = { :letters => ( 1 == 1 ? 'yes' : 'no' ) }

That will give asdf the hash:

{ :letters => 'yes' }

I probably wouldn't use a Proc for something like this... just doesn't
seem to be appropriate. You could always define a quick little method
for evaluating a block inline if you wanted a particularly semantic
option:

def render
  yield
end

used like:

a = { :letters => render { 1 == 1 ? 'yes' : 'no' } }

or, maybe you want something a little different..?

def pick a, b
  ((yield) ? a : b)
end

used like:

a = { :letters => pick('yes','no') { 1 == 1 } }

But that's completely up to you.
