    a / b

"Never" means "integer division" in regular math, so programming languages overloading it to sometimes mean integer division is a common suprise to newbies - especially when it's based on the types of `a` and `b`, which might not be determinable merely from reading the current file. Also, it's not equivalent to:

    a\b ≡ ⌊a/b⌋

As you might expect ( https://mathworld.wolfram.com/IntegerDivision.html ), but instead some round-to-zero nonsense that makes most uses of it on signed integers a bug IME. Some languages give integer division it's own syntax... others overload `a / b` to also mean path concatination.

And while it's not on my top 100 list of C or C++ footguns, it is one of those things that occasionally helps lead to a facepalm-inducing moment when even professionals have a brain fart and fail to consider it's overloaded behavior... or misremember the type of `a` or `b`... or change the type of `a` or `b`.

> That's just not understanding the language.

Learning the footguns and how to avoid them is an important part of understanding any language. That doesn't mean they aren't footguns, just that they can be (partially) ameliorated.
