Exactly. IME, they are excellent for representing UI actions
along with other formal "protocols". They allow you to verify
by inspection that all possibilities are addressed and
addressed in the manner intended -- without having to
count nesting levels of conditionals, etc.
"Will this 'if' cover this condition in ALL states? Or,
does it only apply to some subset of the states, based on
where it is syntactically anchored?"
I'd *not* use one to implement a floating point package...
