There are instances where I get myself in a mess if I do not
type things.  So some I do and some I don't.  Keeps me out
of trouble.  Most times now I do.

One instance where I fly back and forth between strings and
integers is where I am checking revisions.  Is ""
newer than ""?  I do a split on the variable
at the dots, turn the string fragments into integers
and test each position one at a time.  The code was a
nightmare until I started using typing.  That found all
my mistakes with alacrity.  Code came out real elegant
after that.  I was pleased with my ingenuity.

I use .Str and .Int a lot now-a-days too.  Even if not
necessary, it is for maintainability when there is a conversion
going on that I have forgotten about.

In the question I posted the value had to absolutely be a Str
and nothing else.  If anyone added to it and was not
properly turning other things into a string, I wanted it
to instantly fail.

The Str in question was a HTML that was passing
a parts order to Thunderbird to mail to my vendors.
