GCC already has expression statements as an extension.

I don't think it would hurt to standardise this into the language.

return ({

auto i = m.find(x) ;

i == m.end() ? nullptr : std::addressof(i->second);

});

Just write and use a find wrapper like these:

If we start considering solving it via wrappers/helpers, then I would just create something like findOr(key, value) function.

But, anyway, it seems that the idea is not worth it...
Thanks for the feedback.
