Perl has it built in (meta.leading-tabs, meta.odd-tab, meta.even-tab).

I am also using it in Objective-C, using the syntax below which  
itself includes the Objective-C syntax. That recipe could probably be  
used for other languages as well. It works fine with hard tabs, for  
soft tabs it assumes 4-char wide tabs.
