I have seen the join method before but because of my lack
of experience it didn't occur to me to use it.  I bet I
will remember it from now on.  I stuck a few code examples
into my 'snips' directory.

Generator expressions are new to me.  I have seen it's use
but I didn't understand what it was and what it was doing,
until now.  Thanks again.
