André, you mentioned 'auto'... does that include return type deduction?
What about trailing return specifiers?

(I recently posted a useful "helper function" - qOverload - that uses a
variadic template.)

Where are these not supported? I have code that (AFAIK) has been using
these already, and IIRC our compiler requirements are lower.

Besides being inline (template, dontcha know), isn't there an option to
disable those? (Maybe not std::exception one, but at least the Qt <->
STL container conversions?)
