Values and variables

Settled design: let declares a variable, variables are mutable by default, and = is used for initialization and reassignment.

let altitude: Float = 125_000.0
altitude = altitude + 500.0

Numbers may use decimal integers, decimal floating point, scientific notation, and separators between digits:

let entities = 10_000
let gravity = 6.674_30e-11

Implemented lexically: the tokenizer recognizes those declarations and numeric forms and rejects misplaced separators and incomplete exponents.

Provisional design: arrays use [], dictionaries use {key: value}, vectors use <...>, and coordinates use parenthesized lists of at least two elements. Their construction, typing, and runtime behavior await the parser and semantic analyzer. Physical units and coordinate frames are deliberately not distinguished by the initial type system.
