Consider:

struct Foo {
    uint num = 0;

    void incNum() pure nothrow{
        num++;
    }
}


incNum gets marked as PUREstrong, when I feel that it should really be PUREweak as it clearly has side effects.

Regards

I think that this is a duplicate of bug# 5191. If not, it's certainly related.

I would consider it the same issue.

At least, Don's patch in the other report seems to fix it.
