I don't think that numbers could indicate that. The point of that is a single label followed by a bunch of ifs, or by calls to functions that perform tests on input validity. That is, it is the content of the code that causes the problem, not its size. Dan also discourages the use of labels like out, that don't indicate anything about anything, or kmalloc_err, which don't indicate anything about what happens at the label target. julia
