Re: algorithm.sort() seems broken

[andrea]

I would also be nice if:

  * `sort` worked with anything that implements `[]` and `[]=`
  * there was a way to pass a `cmp` argument that is an expression, like in 
`mapIt`, `foldl` and so on, to avoid all these function calls
  * there was the choice between different types of sort (after all, the module 
name is `algorithm`, right?)
