Subject: Re: Immediate if method

Maybe I don't know what you mean by "immediate if"...  meaning "if"
can be used as an expression?

If so, ruby can do this:

if condition then 3 else 5 end.times do { |x| puts x }

Or, more compactly:

(condition ? 3 : 5).times do { |x| puts x }

Or just:

if condition
   3
else
   5
end
