``` You can drop the `:` regardless of if you use the `;` ```html
``` ```html
``` While this might seem very strange (especially because most fully-scoped languages have very rigid syntax), there's a lot of advantages and syntactical niceness as a result of this flexibility. #### Always Be Willing To Take Input While the syntax is flexible, it's not unbreakable. *If you're expecting to pass an input to the directive, you must have the first thing in the syntax be the input value*. For example: ```html
``` Would throw an error at you as it's not valid syntax. Even if you weren't passing a value to the `makePigLatin` prop and only wanted to pass a value to the `makePigLatinCasing` prop: ```html
``` This wouldn't be valid syntax and would still throw an error. However, if you wanted to start a microsyntax with a local template variable definition, this IS valid: ```html
``` This follows the same rules as before where the `;` between the `let` and `casing` and the `:` between `casing` and `'upper'` are both still validly optional.
