[racket-dev] renaming things

This may not be the best place to ask this, nevertheless.

For my own amusement I am creating a language module, and in it I
would like to rename some of Racket's primitives.

Specifically I would like to make a small change to booleans. I would
like it so that #T can be used instead of #t. Racket as it is, allows
that. However, evaluating something like (eq? (quote thing) (quote
stuff)) returns #f, and not #F as I would like .  I imaging this would
'just' be a matter of changing how the printer chooses to output
booleans. My question is therefore, is this possible? Can the printer
be extended in this manner?
