This should work fine. Offhand I'd say the problem
you're having must be of a different nature.

There are shorter/prettier ways, depending on
your individual taste:

E.g.:

def foo(foobar)
  if foobar.nil?
    foobar*4
  else
    "foobar!"
  end
end

Or even:

def foo(foobar)
  foobar ? foobar*4 : "foobar!"
end


Cheers,
