Closes PR 11547.

fa854f62fc Add vector signatures, and `vector-of' to the HtDP signature syntax. 2010-12-19 11:20:51 +01:00

dbd1cfaf10 Don't use teach-equal?' for one-of' signature. 
I did this under the mistaken assumption `equal?' would not work for
cycles, I think.

99e66e0dea Fix cycle detection in `tequal?'. 
... and thus in `check-within', by using an eq? hash table.  Also,
while we're at it, add cycle detection to `tech-equal?'.

Fixes PR #11423.
