`alias meth(labels) = target` in a namespace block makes Ns.meth a call to target with those labels (the target's own parameter names without a list). The engine's 41 table-driven namespaces - 438 methods: Http, Udp, Process, Json, Value, Screen, Input, Audio, World, Tiled, ... - leave emit_ns_call for runtime/native/namespaces.ludic, spliced into every program; 532 lines of compiler go and the seed shrinks by 23k lines of IR. The game's IR is byte identical. The checker checks an alias call's arguments against its target. Still built in: the inline namespaces (Math, Text, List, Vector, Color, Time, Date, ...) and the methods that pick a target by argument type. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# aliases.ludic — L6: a namespace method that is a name for a function. `alias` gives the method,
|
|
# the labels a call may use (in the target's parameter order) and the function it calls; without a
|
|
# label list the target's own parameter names are the labels. This is how the engine declares
|
|
# Http, Screen, Json and the rest (runtime/native/namespaces.ludic), and how a package owns an API.
|
|
#
|
|
# Running it prints: 10 5 3
