Mine probably doesn't do exactly what I expect.
Also, stupid question: I've never seen the double colon syntax for module name as in your example...where is this documented?
Interestingly, this can be called as a fully-qualified method:
module Origin private DEFAULT_TOLERANCE = 1e-7 def self.=~(x : Float64, y : Float64, rel_tol : Float64 = DEFAULT_TOLERANCE, abs_tol : Float64 = rel_tol) (x - y).abs <= Math.max(abs_tol, rel_tol * Math.max(x.abs, y.abs)) end end
Origin.=~(a, b, rel_tol: c, abs_tol: d), or a binary operator without qualification if the defaults are sufficient:
a =~ b. I'm not sure why the former requires qualification.
=~, and the error message says I'm trying to define a setter with more than 1 parameter. I know why this is the case, but maybe a special-cased error for arity-overloading == should exist
