I personally find "Yoda conditions" jarring.
I'm aware that `1 == a` and `a == 1` are equivalent, but I read them
differently. The latter asks something about a, namely whether it's
equal to 1. The former asks something about 1, which is inevitably a
silly question; I already know all about 1. I find that when reading
such code, I have to pause for a moment (perhaps a fraction of a second)
and mentally reverse the condition to understand it.
Note that I'm describing, not defending, the way I react to it.
Writing "=" rather than "==" is a sufficienly rare mistake, and likely
to be caught quickly because most compilers warn about it, that it's
just not worth scrambling the code to avoid it.
If you've internalized the commutativity of "==" so well that seeing
`1 == a` rather than `a == 1` doesn't bother you, that's fine.
But consider that some people reading your code are likely to have
reactions similar to mine.
