[Voted into WP at March, 2010 meeting as document N2993.]

Proposed resolution (October, 2009):

This issue is resolved by the resolution of issue 633.

Notes from the September, 2008 meeting:

The CWG expressed interest in an approach that would define “variable” to include both objects and references and to use that for both this issue and issue 633.

6.3 [basic.def.odr] paragraph 1 says,

No translation unit shall contain more than one definition of any variable, function, class type, enumeration type or template.

This says nothing about references. Is it permitted to define a reference more than once in a single translation unit? (The list in paragraph 5 of things that can have definitions in multiple translation units does not include references.)
