Hello, I read the proposal &q= uot;Forward without forward" has been rejected.

Now, can we please reconsider fixing forward "the right way" e= ven if it involves hacks?

And by "the right w= ay" a mean, of course, let the template param be omitted.
Why is the right way? Multiple reasons:

  • Preserve the API taught for close to 10 years now.
    • actually this is false.std::forward without template param i= s valid and your change would change its meaning.
