This is very nice library with very good and simple concepts. One thing still bugs me. Chaining adds space in between the tokens. This is not always desirable.

This is very nice library with very good and simple concepts. One thing still bugs me. Chaining adds space in between the tokens. This is not always desirable. Adding another function out would solve this (outs would read then outs(pace)). Edit: I noticed while readying the test cases that it is possible to change the separator using outs.sep(' '); I am now wondering how nice it would play with multi threading.
