Great work! This answers [a question](https://discourse.julialang.org/t/eval-a-codeinfo-object/18076) that I’ve been struggling with for a few days now: how to modify a `CodeInfo` object and turn it into a new function. Your code shows exactly how to do this.

Would you mind putting this under an open-source license, so that I can borrow a few lines from your code?
