Styling non-strings

[keturn]

Here are a few test cases demonstrating failures when colorful makes ColorfulStrings out of non-string objects.

s.red(1) + s.red(2) case is particularly fun for generating quirky results that sneak by without raising exceptions.

Not sure how you'd like to handle this.

The thing that seems most obvious to me is for ColorfulStyle.evaluate to str() everything that comes in, so that ColorfulString.orig_string is always a string.

Strictly speaking, that won't be 100% backwards compatible, because you'll be executing the input's __str__ earlier than you would have, and things like ColorfulString.__format__ will no longer call the original object's __format__.

but since style_string freezes its input as a string at that time anyway, it's probably the only thing that makes sense, to do them both at the same time.

And while I'm looking at ColorfulString, I notice __len__ uses orig_string but __iter__ uses styled_string.

Is that intentional? Should __iter__ at least switch on colormode == NO_COLORS?
