Rather than adding complex selectors (which would require more sophisticated string parsing and likely slow down everything), why not be consistent with "not" and allow arrays? Something like:

selector.length && selector[selector.length - 1] !== undefined && !selector.nodeType &&

return this.filter(function(){

jQuery.inArray( this, selector )

})

Then you could do $('code').filter($('pre > code')) which might be slow itself but would not affect other uses of filter.

Oops--WikiFormatting killed my code. Supposed to be:

  !|| selector.length && selector[selector.length - 1] !== undefined && !selector.nodeType &&  
      return this.filter(function(){ 
        jQuery.inArray( this, selector ) 
      })

OK, I can't get WikiFormatting to listen to me. Ignore the first ! in the code above.
