There is a way to implement dynamic language plugins for radare...

A stub generator will be appreciated to create all the necessary
boilerplate to write a single .c file calling the perl/python/ruby
interface from each method hook.

We should define a common and simple way to design those inter-
language communications.

With this interface properly defined we can get some more fun and 
write the language bindings using the same lang-C api.

A simple perl script can be used to parse function signatures and
enums to fill the structures in the proper way (SWIG replacement)

help is welcome!

some random food:

#include <r_lang_lib.h>

static int disassemble(struct r_asm_t *a, struct r_asm_aop_t *aop, ut8 *buf, ut64 len)
{
	LANG_PERL_SET_U8P("$buf", buf);
	LANG_PERL_SET_U64("$len", len);
	LANG_PERL(
	"print \"Hello World $len\";
	$ret = 1;")
	return LANG_PERL_GET($ret);
}

PLUGIN_ASM("asm_ppc", "PPC disassembly plugin", NULL, NULL, &disasm, NULL);
