[racket] Q. about intent of TR wrt floats

I just had trouble with the type of log; I wanted to pass it a positive real, and get back a Real.  After inspecting the type, I see that it works for Positive-Float.  Is this deliberate, in order to get more optimizable code (if the input is a float, we don't need to check it), or just an oversight?  If the former, it seems like there should be some easier way to deliver this information to the user.
