[plt-scheme] to define, or to let

I messed up the question; the final expressions should be:
(list one-variable another-variable)

So what is the difference in the generated code?  Are let-variables 
created differently than define's ?  It seems that a smart compiler 
wouldn't create storage at all in the let version (ie, it would just 
form the list).
