#4822 closed defect (fixed) is a real odd ball

So....NodeList?.style only operates on the first element of a NodeList?, which makes it an oddball since in general, the NodeList? ops operate on the entire list, not just the first element. NodeList?.styles, for example, operates on each element of a NodeList?, so does NodeList?.map, so does NodeList?.filter, etc.

A conversation transpired in IRC that didn't really determine anything concrete, but some of the thoughts were that:

  • NodeList?.style is an oddball and doesn't fit in real well. We're not sure if it's even being used anywhere useful. Plus, it's taking up space in Base...
  • NodeList?.styles makes perfect sense, although "styles" sounds oddly if NodeList?.style were deemed unnecessary and eliminated, perhaps NodeList?.styles would then be renamed to be NodeList?.style
  • If it's absolutely deemed necessary to keep an operation that operates on only the first element of a NodeList?, then perhaps there should be a better abstraction: car and cdr operators. a "car" operator would take NodeList? and only return the first element, which could then be operated on, and a "cdr" operator would return everything except the first element. "car" and "cdr" references for those who haven't dabbled with lisp:

It seems to me that the car/cdr approach seems like a good one. The size incurred by including these ops would be minimal...probably even less than the space that NodeList?.style currently takes up right now. If I were voting, I think I'd either go the car/cdr route or just kill off NodeList?.style all together.
