[Voted into the WP at the November, 2010 meeting.]
N3092 comment US 479.5.2 [dcl.fct.def.default] paragraph 4 says,
A special member function is user-provided if it is user-declared and not explicitly defaulted on its first declaration. A user-provided explicitly-defaulted function is defined at the point where it is explicitly defaulted...
The second sentence should say “user-declared” instead of “user-provided.”
Proposed resolution (September, 2010):
Change 9.5.2 [dcl.fct.def.default] paragraph 4 as follows:
...A special member function is user-provided if it is user-declared and not explicitly defaulted on its first declaration. A user-provided explicitly-defaulted function (i.e., explicitly defaulted after its first declaration) is defined at the point where it is explicitly defaulted; if such a function is implicitly defined as deleted, the program is ill-formed. [Note:...[Drafting note: the suggestion in the NB comment is incorrect. The proposed resolution clarifies the intent.]
