title: How to color function call in Vim syntax highlighting
body: <p>I'm new to Vim and curious how to highlight a function call after the function has been defined. As an <a href="http://imgur.com/tB9xsdg" rel="nofollow">example</a>, in the SublimeText version, totalForArray is green when it is defined, as well as when it is called on line 12. This is what my Vim looks like <a href="http://imgur.com/q2WMQ4d" rel="nofollow">imgur.com/q2WMQ4d</a>, and I'm wondering how to make totalForArray highlighted when it's called.</p>
