How much support or interest is there in the C++ = community for either of these at the minute.

Has a= nyone tried to extend any C++ compiler to add these?

If someone added them in a nonstandard fork, what would be the chances o= f getting them accepted in a mainstream compiler (behind a toggle).


it's absence my biggest gripe in the langu= age (asymmetry between methods & functions, & how it interacts with= header files);

Of everything i've seen, my favour= ite solution is D's UFCS idea. Rusts' traits/impls are ok, but they have th= eir own annoyance (I prefer how open free-functions are)

its' about ease of refactoring between methods/free-function code, a= nd readability (having the convenient chaining/aproximate-infix syntax alwa= ys available)

extention methods wouldn't be expect= ed in vtables, just for compile-time dispatch.
