* propose shorter guide
* add link "About Pull Requests"
Add a link to a GitHub guide on pull requests (thanks to @spdegabrielle)
Remove some text & links to make the un-rendered file easier to read. The missing links are easy to find from the remaining ones.
Include the defined name (in addition to the provided name) in the
result of `module->exports` and `module-compiled-exports` --- but for
backward compatibility, only if the new optional `verbosity` argument
is 'defined-names.
* Fix gen:dict methods for alists with duplicate keys
This fixes https://github.com/racket/racket/issues/2803.
Note that while this works, the implementation is not particlarly fast.
Especially for iterators.
* Fix tabs
* Make code more efficient
* Fix function definition order
* Import set library
* Preserve order
* Use immutable hash sets
* Remove unused import and remove duplicate checks
* Fix syntax error
For a division c+di, when c is less than d, and when (/ d c) produces
infinity, then the sign on the imaginary part of the result was
backwards. For example, `(/ -1.0e-9-1.0e+300i)` produced `-0.0-0.0i`
instead of `-0.0+0.0i`.
Probably makes no difference right now, since these internal functons
rarely show up in the process of optimizing user programs, but just in
case.

Note: the traditional Racket executable continues to incorporate
LGPLv3 code and thus modifications to it must be released under
that license. However, all Racket code in this repository, as well
as the Racket-on-Chez excutable, are more permissively licensed.
Thanks in particular to @otherjoel and @zyrolasting for their work
on this project.
Can't simply use a continuation reified by an attachment
operation, because it is probably a 1-shot continuation
that needs to be promoted.

Commit 77023aeaba made the reference from a custodian-managed
value to the custodian weak, and that could cause a crash in
certain shutdown cases.
Relevant to #2867
