Answer 1

@Sharptooth's Answer makes more sense if we consider this section from the standard:

3.7.3.1 Allocation functions [basic.stc.dynamic.allocation]

[..] An allocation function shall be a class member function or a global function; a program is ill-formed if an allocation function is declared in a namespace scope other than global scope or declared static in global scope. [..]

The above limitation is probably imposed for the very reason that @sharptooth's answer points out.
