tuxn - uxn in tcl/tk

Inspired by the work on uxn5 by @aw and @neauoire I just started an implementation of #uxn in #tcl and #tk. So much fun!

Here is the repo: https://git.sr.ht/~kr1sp1n/tuxn

At the moment I'm a little bit stuck with the implementation.
The opcode tests run fine but it seems that any loop structure is not interpreted
in the right way. Will investigate further when I find some time.
