gollark: Real programmers travel back in time to the start of the universe and alter its initial conditions such that a program they want is simply created later.
gollark: ```mrustc works by compiling assumed-valid rust code (i.e. without borrow checking) into a high-level assembly (currently using C, but LLVM/cretonne or even direct machine code could work) and getting an external code generator to turn that into optimised machine code. This works because the borrow checker doesn't have any impact on the generated code, just in checking that the code would be valid.```
gollark: Mostly designed to stop trusting trust attacks and allow porting, but it could work.
