luk

luk is the .luk language: Lua plus Python-style indented
blocks ("if x:" ... dedent closes it), `fn`, `^` for return,
`:=` locals, `!=`, `elif`, and comprehensions. Explicit
then/do/else/end still works, so any Lua is (almost)
valid luk. Generated Lua keeps the source's line numbers.

The module returns a single function and installs a
require() hook for .luk modules:
local luk = require("luk")
local lua_src = luk(luk_src)
