Subject: confused about '::' vs '.' in method calls

I must admit I'm a bit confused... probably because I never realy 
understood the scope resoultion opperator when I learned C++, but I'm used 
to seeing '::' when you want to show the scope of a method... Foo::Bar() 
means Bar is a method in Foo called like so aFoo.Bar()... now in ruby, '::' 
and '.' seem to be interchangeable... that is I can use both aFoo::Bar() 
and aFoo.Bar() to call Bar on aFoo. In 'Ruby in a nutshell' Matz puts heavy 
emphasis on using '::' for class methods, but the pick-axe book tends to 
favor '.' Does it really matter which way you go? Are '::' and '.' 
functionaly the same? Sorry if this is old hat, but I had a hard time 
making google search the archive for '::' and '.' ;)

Thanks!
