1550. Parenthesized throw-expression operand of conditional-expression

Section: 7.6.16  [expr.cond]     Status: CD3     Submitter: Nikolay Ivchenkov     Date: 2012-09-04

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

The current wording of 7.6.16 [expr.cond] paragraph 2 says,

If either the second or the third operand has type void, then the lvalue-to-rvalue (7.3.2 [conv.lval]), array-to-pointer (7.3.3 [conv.array]), and function-to-pointer (7.3.4 [conv.func]) standard conversions are performed on the second and third operands, and one of the following shall hold:

A parenthesized throw-expression is a primary-expression, not a throw-expression. Should a parenthesized throw-expression be considered a throw-expression for this purpose?

Proposed resolution (October, 2012):

If either the second or the third operand has type void, then the lvalue-to-rvalue (7.3.2 [conv.lval]), array-to-pointer (7.3.3 [conv.array]), and function-to-pointer (7.3.4 [conv.func]) standard conversions are performed on the second and third operands, and one of the following shall hold:

(This resolution also resolves issue 1560.)
