A moment ago, I uploaded the 'bitwise-ops' package. It's a very small module that simply aliases the Racket bitwise functions to use the symbolic names from other languages.

```
<< arithmetic-shift (i.e. left shift)
>> arithmetic-shift, but negates the second argument (i.e. right shift)
& bitwise-and
^ bitwise-xor
bor bitwise-ior (ordinarily |, but that's a special character for Racket's reader)
~ bitwise-not
```
