Well not in the article but I saw somebody doing a guard clause that I started to copy. i.e. ``` let min_id = if let Some(id) = foo()? { id } else { return;

Well not in the article but I saw somebody doing a guard clause that I started to copy. i.e. ``` let min_id = if let Some(id) = foo()? { id } else { return; } ... let bar = if let Some(bar) = baz()? { bar } else { return; } .. // vs if let Some(id) = foo()? { ... if let Some(bar) = baz()? { .. }} ``` It's nice to also do `if let (Some(x), Some(y)) = ...` but sometimes you need the result of `x` to do a few things before you can get `y` (or maybe don't went to evaluate `y` depending on `x`). --- I like the `where` syntax more than the example formatting. ``` fn x<T>(t: T) where T: Foo {} ```
