core features and functions required in modern programming languages

Dear All

Having read/studied a few programming languages I would be interested to know the core features functions etc that would be most desired? I have listed below some features I would like to see.

1. ease of scripting languages with the near speed of compiled ones
2. linked to a core library of functions ie glibc
3. mozilla's XUL
4. SDL graphics opengl library
5. mozilla's XUL linked to 3. and 4.
6. message sending and receiving features such as SOAP WDSL RDF WDDX and RPC
7. bytecode VM that can be translated in the native or targeted host system via a JIT compiler
8. designed mainly for dymanic languages
9. reverse polish notation ie forth and postscript as core language design or used as lower level conversation
10. MACROS like features
11. conditional compilation

any suggestions wellcome!
