I understand what you are saying, but set operators for this 
would be unusual in computing I think. Also, Xor, Nand and Nor 
should work on bitvectors.. so for consistency...

But I think bitoperators should have higher precedence than set 

Lots of trade offs... for sure.

Yes, might be useful for implementing algorithms from papers. 
Crypto etc. Easier to visually check for typos if the code in the 
IDE looks more like the code in the paper.

True, except "~" is used for concatenation that is completely 
unrelated. I think it would be nice to get a quick interpretation 
of code by humans (at least conceptually) by not using the same 
symbols for multiple meanings.

Hard to tell in advance what feels right, worth experimenting
