Yup, the type names for integers (byte, short, int, long, etc.) are borrowed from C#. All primitives in Muon have a well-defined, platform/architecture independent size. Two exceptions: ssize and usize (machine word sized integers), which are mostly used for C interop.

C# programmers should feel right at home, but you're right that there is a very slight learning curve for others.

But, I hear you! I've personally worked a lot with C# which is why I chose the current names, but I realize that there are others that prefer the explicit names (u8, i8, etc.). I'll be adding a type aliasing feature soon, so anyone who wants to define their own alternative type names will be free to do so. At that point it may also make sense to use explicit names as the default.
