Not all people use Emacs, although I use it. So neither Geiser nor Quack
is the same case here. 
My effort is to color the result in REPL only, even for a non-Emacs
user, which is a friendly feature for Guilers.

We know Ruby has many IDEs to do the syntax highlight, but it also has a
gem named 'wirble' to color the result in the REPL.

I think such a REPL-plugin is easy to hack for Guile in few hours, so
I'm going to give it a try.  
The only problem is to output twice seems ugly if I write an independent
module without a patch for 'pp'. Or I don't want to modify the current
REPL code personally.
