As part of Project Manhattan, I am doing a port of the QB64 runtime as well as doing some kernel work.

"QB64 runtime"? Stupid question: is this going to be set up more or less like M$QB, ie. BRUN45.EXE? This would be a good idea to have like 20 or more programs in a single directory with the runtime module and the data (configuration, images, CSV files etc.) they require. Since people keep complaining about the EXE sizes created by QB64 even on 64-bit. I'm sorry if I misunderstand.
Very clever of the OP to port stuff from Python and even using the same keyword in particular.

It will be more like QB.LIB.
