Does anyone know of any existence of a lazy-let macro,

convert from

(if (condition) a b))

Hi,
I have first considered the use of delay/force,
but it turns out that it is a little bit costly.
So, I want it to be done at the complie time.
This should probablly be called let-ahead instead of lazy-let.
Anyway, your macro example is helpful to me.
Let me think again.
Thanks,
Daishi
