A little of coordination for Rosettacode

Right, that's important, but every rule should be followed with a 
grain of salt.

First of all in this program there are no global variables, just 
a global immutable, filename. Global immutables cause far less 
troubles than global variables.

(In my opinion hard-coding the file name like that is not nice, 
but for this little program it's acceptable).

And second, this is a very small program. What's bad in a 100_000 
lines long program is sometimes acceptable in a 73 cloc lines 
long program...
