this looks fragile. Can you make sure it works with more than 1 parenthesis. I.e.:

struct Test {
    static bool constant;
};

bool Test::constant((!false));

I recommend a while loop that skips ( tokens.

Those parentheses are removed by simplifyRedundantParentheses(). Also, this change doesn't make the code more fragile than it already was.
