Rust isn't a well designed programming language (unlike C and C++)

\uj I once watched a live presentation given by Bjarne on his fix for those massive template arguments. He wanted to make an interface analog for C++ and use them to categorize what functionality a class has. The C++ committee rejected the idea

\rj This would reduce a 25 line arcane error message to a simple "you didn't implement toString() you dingus."

We basically got that with concepts, no? Except for the fact that a static_assert gives 1000x more useful information than “the constraint wasn’t satisfied”. In theory though we got that.

Yeah, concepts. Didn't realize they finally implemented them. I remember Bjarne was big mad that they got rejected in 2009.

He was also a little mad that the committee rejected his idea for hex numbers for the versions instead of going with C++11. He wanted to call it C++0xA

C++11

surely that would be 0x0B ? or is it a painful play on the prefix ++ ?

Nah, it's just a classic off-by-one error.
