Amazing

This is amazing :)
Just found we can extend an existing UDT from other modules.

module demo;

import std::io;
import std::collections::range;
macro range(start,end)=>(Range{$typeof(start)}){start,end};

fn void main()
{
    int[] array=range(1,10).to_array();
    io::printfn("array=%s",array);
}

module std::collections::range{Type};
fn Type[] Range.to_array(&self) @inline
{
    if(!self.len()) return (Type[]){};
    Type[] result=mem::alloc_array(Type,self.len());
    foreach(i,e:self) result[i]=e;
    return result;
}
