Sorry, I totally have confused myself (but hopefully not you).

What you're looking for when you do

if(something == false)

is either

unless(something)

or

if(!something)

My point was that you don't need to explicitly check against a
boolean, but then I made things much more confusing.  Sorry for the
triple post!
