XML is pretty far from light-weight. And it's only human readable in theory.
I like the *idea*, but XML is the wrong implementation of that idea. Other than that I think we could agree ;)

hehe, agreed. The problem then is type information.
Consider: ------------- int mf = open("/proc/meminfo/totalmem",O_RDONLY); int32 mem; read(mf, &mem, sizeof(mem)); -------------
Does this work ? Yes of course. But what if I ported my program to a 64 bit arch... The program still compiles. It also runs. But the values are no longer correct. Now *that* is hell.
Same story with ASCII.
I want type information.
