974. Default arguments for lambdas

Section: 7.5.5  [expr.prim.lambda]     Status: CD3     Submitter: Jason Merrill     Date: 4 September, 2009

N3092 comment US 29

[Moved to DR status at the April, 2013 meeting.]

There does not appear to be any technical difficulty that would require the restriction in 7.5.5 [expr.prim.lambda] paragraph 5 against default arguments in lambda-expressions.

Proposed resolution (August, 2011):

Delete the following sentence from 7.5.5 [expr.prim.lambda] paragraph 5:

Default arguments (9.3.4.7 [dcl.fct.default]) shall not be specified in the parameter-declaration-clause of a lambda-declarator.

Additional note (February, 2012):

EWG requested that the adoption of this proposed resolution be postponed to allow them to discuss it. The issue has thus been returned to "review" status pending EWG action.
