Check this out:

Any reason why we couldn't add ~= to the c spec so that we could say:

myVar ~= myFlag;

Which would do the same thing as:

myVar &= ~myFlag;

it's just not consistent. All current assignment "modifiers" are "binary" operators and ~ is unary one.

Cons:

* inconsistent with other compound assignment operators

* looks like regular expression matching operator used in other languages

Pros:

* shortens certain expressions by one character

I don't think it's worth it.

What does the search query have to do with it?

I was just shocked that no language anywhere had thought of it yet. I can't even remember the last time I did a search that came up empty.
