Jens,

I see. So you want to search for `if (!(`

That is 668735 so:

16.5% of if statements are like `if (!expr)`

1.4% of if statements are like `if(!(expr))` (or about 10% of `if(!expr)`
statements)

Got it. Yeah I agree with the ~1% you are seeing.

Note that

yeah and neither can:

   if (!(T) foo)

I checked that occurrences of `if(!` were dominated by `if(!expr)`. I
lightly checked the same is true for `if(!(` and `if(!(expr))`, confident
that its 80%+ at least.

Yup. Typo, other way around.
