AngularJS - Unwatching auto bound values within curly braces

Is there a built-in method to AngularJS to remove the automatically created watch on a value inserted into a template via curly braces.

For example:

<span>{{someVal}}</span>

In my case, someVal is never going to be changed after it's loaded the first time. I don't need the watch code listening for changes. I'm trying to speed up a page's performance that has a rather large table - some values the user can edit but most are read-only values.

I'm not setting up a watch manually so I don't have a reference to the deregistration method for each value. Do I need to write a custom directive to achieve this?

I have recently found a better way of doing it as it's built in the angular:

<span>{{::someVal}}</span>

A buddy of mine found this set of directives for this exact purpose.
