Hey,

So I’ve looked at module\_eval, class\_eval, and Kernel#eval

and I’m pretty sure that what I want to do is to do Kernel#eval(“blah  
…  
some code”, global\_environment)

where by global\_environment I mean the global\_context or the  
global\_binding

The problem now … is that I don’t know how to access this global  
environment / global context / global binding … is there a function  
that I  
can call that will

(1) get me the global binding / global env / global context or  
(2) a function that I can call that will get me the current binding /  
env  
/ context

Thanks,  
(when replying please cc the list and me)
