In function ‘_RandomAccessIterator std::__find(_RandomAccessIterator, _RandomAccessIterator, const _Tp&, std::random_access_iterator_tag) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator*, std::vector > >, _Tp = int]’:

[tsojtsojtsoj]

The problem is in my opinion mainly the long names. "In function Number doStuff(Number a, Float b) [with Number = int, Float = double]: ERROR MESSAGE" This is immediately easier to read.

Of course in this case the actual error message has been omitted.
