I meant opposite. In C "&" has higher priority than "==".

I don't want "a&b == c" to parse as "a&(b==c)".

So I want "a∧b == c" to parse as "(a∧b) == c".

I am adding keywords "or", "and" "not" for boolean logic. And 
adding a special quotes «identifier» for creating identifiers. So 
if you in current D have "and(x,y)" then it can be transpiled to 

I believe HackerPilot has a scanner-library that can be used for 
automatic code conversion.

Well, it depends on what kind of software one writes. You could 
also view an unsigned int as a vector of bools rather than a set.

Nand and nor might be nice to have, not sure if people use them 
much, but.

I looked at that one, but it is virtually indistinguishable from 
a regular C. I guess it could work if one required it to be used 
like a function:

So allow "∁(MySet)" and disallow "∁MySet" and "MySet∁"
