I'm currently writing a language similar to lua/python in syntax. It creates exectuables with build-in vm, and the bytecode instructions are written with fasm (that's why I credit it here). The point ot the language is absolutely cross-platform generation (currently has win pe32 and linux elf32) of small, fast executables (something like the PureBasic project, but the language is object oriented, fully dynamic and not native). Actually I have almost finished compiler with linker (70%) and currently no libs (but that will be easy to do with the compiler). I'm very serious about this project and soon I'll post webpage with current status, if someone is interested.

wow it would be very cool if you make this language open source. It would be nice to have a dynamic language written in fasm ... maybe it can beet the c-written dynamic languages in speed?

I seriously doubt that, you would have to write the language in very "low level style" to have some real gain from assembly, and then it would be hell to maintain.

Nil is C-written (for portability), but the real instructions templates are generated using fasm and listings. Ex: my_bytecode_push0 -> push 0, etc.

If you keep the Python white-space indentation crap I will hunt you down

python indentation is fantastic grow up!

be cAREFULL
THE "NIL", in french; is subject to flooding

or you could write the bytecode compiling mechanism in fasm, or have it translate to pure machine code, that way you can write the next version of it in itself
