Idiom #252 Conditional assignment

Assign to the variable x the string value "a" if calling the function condition returns true, or the value "b" otherwise.

x = if condition
      "a"
    else
      "b"
    end

Does not repeat x.
x = condition ? "a" : "b"

x := (if condition() then "a" else "b");
