__builtin_inline!
Add an experimental `__builtin_inline!(c_expression)` special intrinsic which run a C code snippet. In `c_expression`, you can access the following variables: * ec (rb_execution_context_t *) * self (const VALUE) * local variables (const VALUE) Not that you can read these variables, but you can not write them. You need to return from this expression and return value will be a result of __builtin_inline!(). Examples: `def foo(x) __builtin_inline!('return rb_p(x);'); end` calls `p(x)`. `def double(x) __builtin_inline!('return INT2NUM(NUM2INT(x) * 2);')` returns x*2.
