Cyclic Dependencies

[William-Weston]

Greetings and salutations. First, thank-you for making your code available. I'm also trying to implement the jlox tree-walk interpreter in C++ but I'm having some problems. Based upon a cursory examination of your code, I can't tell if you dealt with this issue but I figured I might as well ask.
How did you deal with the cyclic dependencies between the environment and a lox function? The environment holds the function but the function also holds a shared_ptr to the environment. I'm not a professional developer so I'm not sure how to deal with this problem. I end up with memory leaks. Thank-you.
