I come to praise .join, not to bury it...

Even with my newfound understanding, provided by the Martellibot, I
agree with this.  Calling a method on an object is fine.  Calling it
on a literal looks weird.  Take for example something like this

three = 1.__add__( 2 )

;-)


Anyways, after seeing part of the discussion here I tried a string
method on a string literal in Java and it worked as well.

I still sort of disagree with string methods like 'replace'.  After
all, it doesn't really replace anything.  It creates a new object with
the proper differences.  Perhaps if 'replace!' were also added to
it might be clearer.
