18. Deliberate exclusions

Not in Luce, with the reason: integer widths and unsigned integers (one number of each kind); bit operations, shifts, wrapping and saturating arithmetic (Base); char (a scalar is a str of one); fixed arrays, slices as views, unions, pointers, spans, atomics, asm, allocators, defer, new, free, weak as a word (memory is not the programmer's); inheritance, overloading, variadics, default interface methods, associated types, downcasts (one way to do each thing); exceptions, force unwrap, nullable-by-default (failure is visible); extern, cfunc, C++ bridges, an audited tier (the machine is a Base package); macros, reflection, conditional compilation, build scripts (the language is the language).
