In the second version of (1), there is no difference between C++11 and C++17 listed.

I suppose constexpr is missing? — Preceding unsigned comment added by 83.236.148.156 (talk • contribs)

Yes. Fixed, thanks! T. Canens (talk) 00:26, 11 May 2016 (PDT)

Why does the for_each example take Container by rvalue reference? It never std::forwards the parameter anywhere.

probably FJW had something it mind when it was added, but it does appear to be unnecessary. --Cubbi (talk)

So that you can call it on rvalue containers too? It's basically used as a "universal" reference that accepts everything. T. Canens (talk) 12:51, 20 September 2016 (PDT)

oh, f(*it) could be mutating, that's why? --Cubbi (talk) 21:44, 20 September 2016 (PDT)

In declaration #2, i have a question about the parentheses. In the declaration template< class T, std::size_t N > constexpr T* begin( T (&array)[N] );, are the parens around &array necessary, because without them, this declares a function taking an array of N references to T, which is disallowed by the standard?

[edit] "See below" points to nowhere

The "see below" for (3) points to nowhere, as there's nothing, further down the entry, about the conditional noexcept. 93.62.124.8 09:26, 3 May 2018 (PDT)

It points to the Exceptions section. T. Canens (talk) 19:22, 3 May 2018 (PDT)

Aha! I had missed it, thanks! Maybe changing "see below" to "see Exceptions"? 93.62.124.8 07:38, 4 May 2018 (PDT)
