Presumably it's poosible to write my own read routine that parses.

Then perhaps I could write my own let macro to expand my let into 
whatever works in gambit -- presumably something that uses the 
standard let macro.

Is there some namespace mechanism that could allow me to distinguish 
the two let's?

If not, I suppose I could have the variant read routine read 
every symbol let into LET or lett or something else ugly.  But this is 
ugly and nonmodular, and I'll probably have a few more cases like this; 
I'd prefer something clean.

And how do line numbers from the original source coded get embedded 
into the S-expressions so that the interpreter (and, presumably the 
compiler) can use them when reportin on errors?
