Jonathan M Davis <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |m --- Comment #1 from Jonathan M Davis <[email protected]> --- Yeah, this is one of those that's usually surprisingly hard to figure out. I usually end up doing a lot of examination of template constraints before I figure out that I simply forgot the !. It's a lot more obvious in this example, because it's short, but one you start chaining templates or having complicated predicates, it quickly becomes non-obvious that the ! is missing. --
