Alternatives to C/C++

Instead of sticking with C/C++ for performance consider:
1.Free Pascal -Small memory use,very fast, easy debug
2.OCaml - medium memory use, fast,very terse, functional and secure.
3.FreeBasic - very fast,easy to use, low memory use, supports QBasic code as dialect. Other Basics to consider: PureBasic/Gambas/PowerBASIC
4.Digital Mars D- fast, easy to write and debug, large library, transition from C/C++ much easier.Garbage collection can be turned off.
