Hi again,

I must be missing something really obvious but I'm having a really hard
time figuring it out. Once again I hope that someone could enlighten me.

I'm doing the following with ruby 1.6.6

#include "ruby.h"

int main(void)
{
    int state = 0;
    ruby_init();
    rb_eval_string_wrap("a = 5; puts a", &state);
    rb_eval_string_wrap("puts a", &state);
    return 0;
}

Which gives the following result then I run it:
$ ./test6 
5
5


Why does it print 5 the second time? What I thought by looking at the
code for rb_eval_string_wrap was that each call to rb_eval_string_wrap
would execute in its own context, in an anonymous module. But
apparently that's not happening. So what should I do instead if I want
each call to be executed in its own context? So that local variables
would just be accessable during the call and not during later calls.
