This is what I try archive:
Idea is have stackfull corutine with local memory allocation. Idea is
that you can have multiple corutines start in one function and each
have its own buffer.
This code do not compile because standard forbid code like:
void* operator new(std::size_t s, LocalStack& ls) noexcept
//auto p = ::operator new(s);
auto p = ls.curr;
ls.curr += s;
std::printf("new %p\n", p);
void operator delete(void* p, LocalStack& ls)
std::printf("delete %p\n", p);
ls.curr = static_cast<char*>(p);
// ::operator delete(p);
There is now easy way to have this `LocalStack&` for `delete`.
Right now only way I see is add special code to `task<>` destructor
and pass information other way to correctly release memory.
