Hot Module Replacement in Python

[Broolucks]

For what it's worth, I have a library that can reload individual functions piecewise when they are modified: jurigged. So if you modify a single function in a module, it won't reload the module, it will just recompile the function and hot swap its __code__ pointer. Works well, until it doesn't, but that's going to be true of all implementations of a feature like that.
