Remove Class Not Working With Mootools

I'm using the following piece of code in my webpage to change the class of select elements depending on the choice of a radio button. The part where I add the class works fine but

Solution 1:

It doesn't work because the MooTools ".removeClass()" method simple-mindedly jams the class name into the middle of a regex without bothering to escape embedded regex meta-characters.

You can, however, work around the problem by doing the appropriate quoting yourself. In this example, it'd look like this:

 $('first_name_conjoint').removeClass("validate\\['required','nodigit'\\]");

Here is a jsfiddle.
