Hi,

I would like to suggest this new feature that may be useful: a custom global attribute as a DRY and KISS feature for sharing some repetitive coding or verbose styling. It is a bit familiar to Angular directive concept, but it is more functional and react-like.

• alternative 1: using @ token in component attribute working as a function injetor

const glyphIcon = (elm, val) => elm.className = "glyphicon glyphicon-" + val + " icon";

<div @glyphIcon="ok" >...</div>

• alternative 2: function decorators (not support in ecmascript) would be nice for kebab-case notation

@directive("glyph-icon")
const glyphIcon = (elm, val) => elm.className = "glyphicon glyphicon-" + val + " icon";

<div glyph-icon="ok" >...</div>
