What C++ Does Wrong

Summary
When it comes down to it, C++ does only one thing wrong, it tries to be everyone's language.

Most reasonable complaints I have heard, and made, about C++ comes down to the same basic flaw, it tries to be the general purpose language. This is what makes the language so darn hard to use.

So how do you fix it? Well I think the specification should be split up. People writing C++ for PC's, really don't care about portability to embedded controllers! The problem is that you can't rely on the specification to give you anything concrete, not even a filesystem. I mean seriously, just because a handful of embedded micorocontroller programmers want to use C++ (incidentally most don't use true C++), does that mean the rest of us have to suffer?

So what is the solution? Well the standard should fork the specification into different branches. If I were designing my own language (which I am) I would encourage different specifications to branch off of a shared core specification (which I will do).

What I would want from C++ would be a core specification, and a sub-specification for PC's, and another for embedded microcontrollers. Unfortunately the committee is ignoring this, and we have the needs for these specifications being filled inadequately by Microsoft's Managed C++, and EC++. EC++ is a subset of C++, which is unfortunately the wrong way things should be going. If there is going to be an EC++ which is a subset of C++, then why is C++ continuing to be under-specified? I think C++ should allow EC++ to satisfy the embedded controller market and focus on supporting the machines where there is still substantial use.

Imagine the possibilities of C++ specification which integrated a linear memory model, 32 bit word size, threads, a filesystem, etc. I think C++ is spelling out its own demise, by refusing to modernize.
