Output API

printLine(value) is the single-line standard output primitive. For batch output, import std.io.printLines. Its public declaration is defined by io/output.norm.

Void printLines<T extends Stringable>(Iterable<T> values)

Elements are printed one per line in Iterable<T> traversal order. Stringable is the standard interface declaring String toString(); the compiler provides witnesses for basic scalar types, while custom types must explicitly implement the interface. A literal containing different concrete types uses Stringable as its element type when they share that interface.
