Something should have just clicked in your brain, and every piece fell in place, but if not, read on.

Yes, the light bulb has gone on. Thanks to you and Brent. I really appreciate both of your explanations to my follow-up question. It’s almost a bit difficult to keep up with responding while reading your excellent and very helpful responses. I do think I now understand what was going on in this particular instance and why I was tricking myself. It always seems so simple in hindsight. I’m sure this won’t be the last time I get tripped up on this though. But I’m hopeful I can better reason it out going forward.

Thanks again for all the extremely helpful responses.

Glad to be of help! For what it's worth, the whole numeric-types-and-type-classes thing is definitely one of the trickiest corners of Haskell, at least when starting out. I remember spending a good deal of time struggling through it at first too. -Brent
