TIL Rust has an ambiguity `if Foo {}` -- is `Foo` a value of type bool, or a struct? Rust solves this by defining a grammar production 'any expression except struct literals' and using it in this position.

I've been doing more functional programming recently, and realised just how general a for loop is. We needed a function `int list -> (bool, int) list` that would mark each item if it was the largest seen so far. Pretty straightforward.

I never know whether to write bool or boolean. I try to avoid excessive abbreviations, but bool is so snappy and very common.
