Function body value names not looked up in function parameter scope

f0 = function (s) module cube(s);
m0 = f0(10);
m0();

f1 = function () module cube([5,10,20]);
m1 = f1();
m1();

WARNING: Ignoring unknown variable 's' in file test.scad, line 1

However there is a graphical output of the cube from m1();

For anonymous modules you can use the following syntax. Essentially you need to create the module_literal and get a reference to it in local scope, then return a reference to the module with function call args

function f (pos ,size) = 
   let ( m1 = module (p, s) { translate(p){cube(s);}})
module m1(pos,size);

m = f([100,50,50],[20,30,40]);

m();

For functions with arguments returning a module with arguments,
e.g https://libera.irclog.whitequark.org/openscad/2022-10-01#33072095 (There proposed using pseudo syntax as
fm = function (x) module (y) cube([x, y, 2]); fm(3)(5); )

Currently this can be done as follows:
Any function arguments used in the returned module should be added as default arguments to the inner module m parameters as follows. Here the argument x of function fm, used in the returned module m is made a default argument of the module literal parameter x1 and the parameter x is then used in the module arguments

fm = function(x) 
  let ( m = module(y,x1 = x) cube([x1,y,20]) )
m;
(fm(30))(50);  // instantiate the module returned from fm 

This can be shortened to

fm = function(x) 
  module(y,x1 = x) cube([x1,y,20]);

It would be possible to optimise this but this workaround seems satisfactory at the moment.
Also currently default arguments need to follow non default arguments.
