[Voted into the WP at the July, 2009 meeting as part of N2927.]

Although the term “move constructor” appears multiple times in the library clauses and is referenced in the newly-added text for the lambda feature, it is not defined anywhere.

Notes from the June, 2008 meeting:

The only reference to “move constructor” in the core language clauses of the Standard is in 7.5.5 [expr.prim.lambda] paragraph 10; there are no semantic implications of the term. This issue will be addressed by using a function signature instead of the term, thus allowing the library section to provide a definition that is appropriate for its needs.

Proposed resolution (July, 2009)
