Local variables (parameters) are highlighted as types in an if statement, when using the official Lezer cpp package and classHighlighter.

Example (image):

I understand that it can be complicated to differentiate variable and type names in C++, but still. Maybe it would be better to avoid type tokens at all, if it's too complicated to recognise them correctly.

Code of the example:

int digits_to_number(int a, int b, int c) {
    int mag = abs(a) * 100 + abs(b) * 10 + abs(c);
    if (a < 0 || b < 0 || c < 0) {
        return -mag;
    } else {
        return mag;
    }
}

Attached patches, released in @lezer/lr 1.4.5 and @lezer/cpp 1.1.4 should improve this.
