914. Value-initialization of array typesSection: 7.6.1.4 [expr.type.conv] Status: open Submitter: Gabriel Dos Reis Date: 10 June, 2009 Liaison: EWGAlthough value-initialization is defined for array types and the () initializer is permitted in a mem-initializer naming an array member of a class, the syntax T() (where is an array type) is explicitly forbidden by 7.6.1.4 [expr.type.conv] paragraph 2. This is inconsistent and the syntax should be permitted.
Rationale (July, 2009):
The CWG was not convinced of the utility of this extension, especially in light of questions about handling the lifetime of temporary arrays. This suggestion needs a proposal and analysis by the EWG before it can be considered by the CWG.
