Google Closure compiler warning for RegExp

Question

When compiling a Javascript file using the Google Closure compiler set for Advanced Optimization, I get the following warning:

WARNING - References to the global RegExp object prevents optimization of regular expressions.

The warning is being triggered by the following line of code, which I believe is fine.

        rv = parseFloat( RegExp.$1 );

What keyword can I use in a Suppress construct of the following form for suppressing the aforementioned warning:

/** @suppress {need_keyword_here} */

Answer 1

/** @suppress {checkRegExp} */ does the trick.
