    emiT-C

    emiT-C

    A time travelling programming language

    emiT is a language all about parallel timelines.

You can kill variables, which destroys them permanantly- at least until you send another variable back in time to kill the variable doing the killing. This very quickly leads to a lot of confusion, with a constantly changing source code and the very easy possibility of creating a paradox or a...
