--- Comment #14 from Robert Dubner <rdubner at gcc dot gnu.org> --- "Wait for me! I am your leader!" I am not *used* to this. What I *am* used to is people telling me there's a problem in my code, and then standing around tapping their feet impatiently until I fix it. Okay. Deep breath. Because I am totally curious, I am going to download Richard's patch and apply it so that I can at least see what's going on. It has taken me a ridiculously long time to figure out that you are creating trees for numeric values, and then doing arithmetic on those trees at compile time. That's a methodology that simply didn't occur to me *at all*, and it's causing the ground to shift beneath my feet. It's disconcerting. And what I am seeing here is a rampant enthusiasm bordering on glee for improving the front end. And I simply have to get past the idea that *I* have to fix everything. So: I am basically asking: "What can I do?" I offer up as an answer: "Bob, we need more test cases." Does that sound right?
