In DrRacket, the "preserve stack trace" button actually corresponds to a
mode in the compiler that disables some optimizations [*]. The radio

This is what ->i is for. The syntax of define/contract is slightly
misleading because it appears to place the contracts in scope of the

Place channels are asynchronous, not syncronous (i.e. you don't have

DrRacket doesn't currently know about the difference between those two

doesn't currently tell).
There is a related thing, tho: when debugging is turned off, if you

I think it would be nice if there were a new library, pulled out of
the current slideshow/base that exported more pict-making functions
and didn't depend on these various things.
I've looked into this before and I came to the conclusion that it
didn't belong in pict because of the way it does
Generate multiples of those and combine them (shifting old ones over
and adding new ones as the lowest digits)?
I'm not sure of a good way to generate nats uniformly at random where
you don't specify an upper bound, but Neil Toronto suggested something
crazy we used this paper:
It is control-left and control-right to go by words in DrRacket. If
you go to Edit|Keybindings|Show Active Keybindings and type "word"

I have been bitten by this one too, it is a bit pernicious. Perhaps we
can adjust the documentation to make more clear that `else` isn't
special in `match`?
