Sobotka: Why GIMP is inadequate

A similar problem applies to dynamically typed languages like python though. The interpreter can't possibly know whether the type of a function argument satisfies the requirements of the function it is passed to. The difference being that a C++ compiler will point that out at compile-time, while a dynamically typed language won't throw up until run-time, much less give you a sensible error message.

Poor implementations are also part of the problem. g++'s error messages are worse than they could be, for example it always talks about std::basic_string<char, std::char_traits<char>, std::allocator<char> > instead of plain std::string (the latter being a typedef for the former). Clang++ is supposed to be much better at this, though I haven't tried it yet.
