One thing I never understood about this: why does this not just compile to Lean so they're compatible with each other? Having a good interface is admirable, but the difference between set and type based foundations seems not very important and porting any enough math to sustain Litex seems like a huge undertaking.

It's truely great if Litex does compile to existing formal languages. The only problem is that we can not find a good way to compile our verification process, which does not require users to give names to facts they are using and thus very different from how Lean works, to Lean (set theory example is just the first one of a series of comparisons). Besides, it's even harder to compile future functionaliteies, like printing out results of each statement of litex in a human readable way, to lean. So since litex is still a young language and we are using our limited resources to try new ideas and crack here and there, for the time being we believe it's not a good time to migrate our code in such a great scale. Thank you. Merry Christmas.

To be honest I'm not convinced by the technical downsides you mentioned here BUT I can see why you wouldn't want to spend time on this if it takes away from language development. Thanks!
