-- Records: named types with fields. Construct with type-name, access with dot.
-- `with` creates an updated copy (immutable update — original unchanged).
-- Destructure with {field;...}=record to bind multiple fields at once.

type pt{x:n;y:n}
type person{name:t;age:n;active:b}

-- Construct and access a field
make-pt>n;p=pt x:3 y:4;p.x

-- Access a different field
coords>n;p=pt x:10 y:20;p.y

-- Immutable update: access updated field
move-x>n;p=pt x:1 y:2;q=p with x:99;q.x

-- Verify unchanged field after update
move-y>n;p=pt x:1 y:2;q=p with x:99;q.y

-- Update multiple fields
reset-x>n;p=pt x:5 y:5;q=p with x:0 y:0;q.x

-- Destructure a record
dest>n;p=pt x:7 y:8;{x;y}=p;+x y

-- Construct a person and check a field
