Scala's library has a similar method.  I thought it was the silliest,
overly specific method I've seen, but then I keep finding myself using
it!

This is my experience, too.

It seems people just cannot resist the urge to generalize this method
more than is useful.  We've all taken too *many* programming classes,
and are overlooking some pragmatics!

Scala's method is actually more general than the join: methods being
passed around -- it takes in an initial string and a final string as
arguments -- but I find myself always setting those to the empty
string...
