moving TypeTraits to the boost::type_traits namespace

I think we should finally move TypeTraits to the boost::type_traits namespace. This has only advantages: - clear separation from other boost libraries - the boost namespace is no longer contaminated - when providing additional TypeTraits, it is immediately clear in which namespace they must be implemented These changes would of course be elaborate, but they would bring advantages: consolidation + general review of existing TypeTraits: - are they still necessary / could they be removed? better to use std::TypeTraits - could they be implemented in a more contemporary way?

boost.parser: Hitting the wall; what am I doing wrong?
by Richard 03 Nov '25

Hi Boosters, I've hit a wall while using boost.parser to parse a fractal formula file format. At this point, when I attempt to add a new rule to my grammar, msvc goes to compile the file and just sits there. It isn't hammering CPU, memory or disk, just sitting there. I let it run for like 30 minutes before I aborted it. There's no error or warning diagnostic. The details are in this issue on boost.parser: <https://github.com/boostorg/parser/issues/288> I believe separate compilation of the rules implementing my grammar would work around this problem (and give me better turnaround time on edits as I'm not changing the entire grammar as I improve it), but I was unable to get separate compilation of rules to work with boost.parser. Is separate compilation even possible? -- Richard -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Terminals Wiki <http://terminals-wiki.org> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> Legalize Adulthood!
