More generally, is there a generally accepted strategy for Boost
libraries to attempt to force compilers to emit useful diagnostics?

I can imagine there are a number of places where this goes on, and so if
anyone has good domain knowledge about coercing compiliers into emitting
useful diagnotics, it'd be great to have that written down somewhere (or
maybe even turned into some macros possibly).

(Kinda a vague idea-specification, I know.)
