operator new(size_t) is useless because when calling new thread_data lookup doesn't go to outmost namespaces and overload resolution says no, no overload

The "won't be called" stuff that actually "might be called" makes me uneasy. If those certainly won't be called, and given that's a requirement for the program to be well-formed, why not enforcing that requirement by the design?

[AntonBikineev]

@K-ballo ugh, the first point is absolutely correct, thanks.
In what scenarios that operator new(size_t) "might be called"? What do you suggest? I personally don't like those run-time assertions and would rather prefer having it deleted and link-time errors.

@AntonBikineev can we close this now?

[AntonBikineev]

@hkaiser think so
