Well ruby should enforce as much as it can, but you should remember that 
while you can do this on linux:

vita@vita-desktop:~$ echo something > bla
vita@vita-desktop:~$ echo something > bla.
vita@vita-desktop:~$ ls bla*
bla  bla.


the windows version will have different result no matter what:


C:\temp>echo something > bla

C:\temp>echo something > bla.

C:\temp>dir bla*
