Title: Interact namespace with all other namespaces

Hi John,

Zhen (pierce1987) is interning with me this summer and as a warmup implemented interacting a namespace with all other namespaces using ```-q x:``` and ```-q ::```.

It is implemented syntactically by expanding all combinations of printable characters.
