This was what I wanted to express, though I could not write it in such a striking
sentence  :-)

I don't know what is right nor wrong...

Maybe make __FILE__ a class with a one useful method, #standalone?
So that instead of 'if $0 == __FILE__' you can type 'if __FILE__.standalone?'

Maybe make a System class, containing a $0 replacement?

What does other languages do ?
