Au contrare it is C which is handicapped. How handicapped is C++ considering it subsumes C, can use C right at the source level, has an inline FFI, and yet C++ libraries can't be called by C because C++ provides type-safe linkage. Advanced languages are advanced because they improve on C and this inevitably means they must go beyond C. This is why such languages require setting up an environment, usually by providing main(). Even if you could set up an environment with a C function call, which is trivially achieved by replacing main with mymain(), you would simply be starting a foreign environment, not providing a library of functions which could be individually called by C. My system Felix (http://felix-lang.org http://felix-lang.org) is specifically designed to live with the compromises of C/C++ compatibility, but you still cannot put arbitrary Felix code in C callable functions because Felix provides an advanced environment supporting, for example, fibres with channels. Fibres are scheduled by returning control to a scheduler so they cannot be nested inside a function which puts its return address on the machine stack. If you Felix write code without using features requiring advanced support that code can be made into a C callable library (both static and dynamic linking is supported). Felix is probably better at C/C++ integration than any other language except C++.
