# namespaces.ludic — the engine's namespaces that are a name for a runtime function: `Http.get`
# is `http_get`, `Screen.fill_rectangle` is `fill_rect`. Each `alias` names the method, the labels
# a call may name its arguments by (in the target's parameter order), and the function it calls.
# Spliced into every program, and costs nothing until a method is called: the file that defines
# the target is spliced by its own use. A package declares its namespace the same way (L6).
