Starting Class or Method Names with Numbers, Why Not?
<p>I recently was quickly shortening some method names in a javascript file and ran into a problem when I converted one method name: </p>

<p>Before: </p>

<pre><code>RefreshSevenDayGrid(){
   // some stuff
}
</code></pre>

<p>After: </p>

<pre><code>7Day() {    
    // some stuff
}
</code></pre>

<p>I quickly discovered that the javascript no longer worked. I heard from several people that numbers should never be used for Method or Class names. Is there ever an exception to this?</p>
