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. https://rust-lang.github.io/rfcs/0092-struct-grammar.html

It's odd how lazy evaluation is generally seen as a niche design choice, yet the vast majority of languages treat `foo() || bar()` as short-circuiting.

When a tool supports both regular expressions and literal strings, which should be the default? If you default to regex, users can match more strings than they realise (e.g. `foo.txt`) or less (e.g. `foo(bar)`). I typically see regex as the default, but I prefer the opposite.
