Discussion:

One of the motivations for incorporating seed_seq::size() was to simplify the wording in other parts of 29.5 [rand]. As a side effect of resolving related issues, all such references to seed_seq::size() will have been excised. More importantly, the present specification is contradictory, as "The number of 32-bit units the object can deliver" is not the same as "the result of v.size()."

See N2391 and N2423 for some further discussion.

Proposed resolution:

Adopt the proposed resolution in N2423.

[ Kona (2007): The LWG adopted the proposed resolution of N2423 for this issue. The LWG voted to accelerate this issue to Ready status to be voted into the WP at Kona. ]
