Consider the following example:

``` struct X {};

struct Guard { explicit Guard(int) {} Guard(Guard&&) = delete; };

variant v {}; v.emplace<Guard>(1); ``` ... The documentation is correct, the implementation is wrong here; this should work and the fact that it doesn't is a bug. Thanks.

Might I ask how you plan to fix this bug?

It's fixed in https://github.com/pdimov/variant2/commit/9f7e525984ac87ccb90799c9bb2283946d....

Go double-buffer in this case?

There's no reason to double-buffer here, because X is nothrow default constructible, so it can be used as a fallback type.
