Sure. I'm not arguing that Python's choices of what's truthy or
falsey isn't consistent or hard to remember. What I'm saying is that
I personally have to deal with multiple languages at once these days.
seem needlessly divergent is truthiness. Given that, I personally
subset the language so that I don't have to spend brainpower on this
As a confession: I have run and introduced bugs where the root cause
was one language's truthiness table diverging from another. Given
that I recognise that I make this particular class of mistake a bit
more frequently than I'd like, I try to account for this personal
weakness and engineer for it. I am not clever.

I don't understand what your response here means. My intent in
quoting Matthew 5:37 was purely as a joke, precisely because the quote
is so ridiculously out of context and definitely not intended to apply
to the boolean context of programming languages. My apologies if you
didn't like that.
