The truth about the let keyword

In Scopes, the let keyword is an immutable binding to a name. Sometimes we call them register variables, which is an LLVM-ism. Because it's just a binding with no location in memory and a completely abstract construct, you can alias things that aren't necessarily values, like types or keywords. You can bind anything to a valid symbol; you could even shadow let itself.

Then how do I mutate data?

You can mutate 3 different types of values in Scopes: stack variables, global state variables and mutable pointers.

• Stack variables are declared with the local keyword. They expire when you exit the function frame (ie. return).
• Global state variables are declared with the global keyword. Their memory location is static and always available. It's always safe to take a pointer to global data (although it might not be to do so from multiple threads).
• Pointers are addresses to a memory location. You can take the address from a local, global or through memory allocati

Most stuff is handled by Noctalia Shell. My configuration sort of assumes you have KDE plasma installed already, otherwise you have to install a handful of utilities individually. Stuff I had to fix:

    ELECTRON_OZONE_PLATFORM_HINT "auto"
    ELECTRON_OZONE_PLATFORM "wayland;xcb"
