Accessing a pointer map value requires an or {} block outside unsafe.
math.vec module for generic vector math including 2D, 3D, and 4D vector operations.

Const functions: const y = term.yellow, then println(y('abc')).
Lots of work on x.json2, the pure V json encoder, soon to become official.

Generic typeof[T](), sizeof[T](), isreftype[T]() functions.
New official AdventOfCode repo with AOC solutions, also added to CI.
