Created February 19, 2013 03:29
Ruby implementation of the `butif` construct, which turns a regular `if` statement upside down. Do something in the normal case, unless this other condition is true then do something else instead. This construct mirrors the kind of thinking that creates the logic one often finds in formal requirements documents.
class Butter
def initialize(block)
@block = block
end
def butif(cond)
if cond
yield
else
@block.call
