Consider adding a style checker rule to remind folks to use toText rather than static_cast<Text*>

Checked Tools/Scripts/webkitpy/style/, but did not get much idea how to do this. :(

I was trying to report the style check error with one of the error category mentioned in BASE_FILTER_RULES in Tools/Scripts/webkitpy/style/checker.py. As far as I understand, errors reported with this list is ignored.

If any of these errors are false positives, please file a bug against check-webkit-style.

This error is expected as it is caused by the new style-checker added in this patch.

Oh, I meant to make the style checker change in a separate patch, but this seems fine too.

It looks like there wasn't a unit test for the style checker change.

Please add one -- otherwise it may break at anytime due to people changing the code and no one will know!

Sure I will add the unit test case. I did not know that there is a unit test suite for style checker. What is the script used for running the unit test?

This comment doesn't seem to be adding any value.  It's redundant with the function name.
