In my experience, it helps often to avoid using strict typing unless
really needed.

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 "12.3.4.1"
newer than "111.3.4.1"? 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.
