This is a little python script that eats some new debug spew and spits out a DOT file. I made it for seeing why recursion wasn't compiling correctly in some files. It draws some boxes/circles/lines that try show all traces and guards and how they connect together.

Example of output:

function fib(n) {
    if (n < 2){ return 1; }
    return fib(n-2) + fib(n-1);
}

print(fib(22));
