Hi Sam
that is too bad I did not know about that, good you showed us.
Maybe   you like the following code(1):

     v = @cache[i] and return v

but I agree that

    return v if v = @cache[i]

 would be nicer

(1) some people wondered recently why "or" and "and" have such low a
precedence, I guess this example is a reason behind this.

Sorry I cannot do that

Post-modification looks better for that.
