-- Example usage inside a NamedNoiseExpression
local noise = require("noise")
local tne = noise.to_noise_expression

data:extend{{
  type = "noise-expression",
  name = "compile-log-test",
  intended_property = "elevation",
  expression = noise.compile_time_log(2000, noise.var("y"), tne(100) - noise.var("distance"))
}}

-- When "compile-log-test" is selected as the map type and a map preview or map is generated, this logs:
--  Info data-updates.lua:24: 2000.000000 reference to variable 'y' subtract
-- Furthermore, the elevation noise expression is set to 'tne(100) - noise.var("distance")', producing a circular island with a 100 tile radius
