[webkit-dev] Feature announcement: Custom Elements

[Hajime Morrita]

Hi Maciej, Thanks for your attention!

the implementation/scaffolding be outside the ifdef?

It should be comprehensive. So it will.

Although some trivial inline stubs, like just returning null or false, or
even doing nothing, will be outside the flag
for minimizing if/def disturbance, they'll be optimized out by compilers.

Also, some kind of refactoring might precede to make new features fit in
the code. Such refactoring will be aimed to achieve clear separation of new
additions by, for example, introducing better encapsulation. (Please note
that this is just a general direction of the change. I have no concrete
refactoring plan in my mind at this time.)

As an example, here is the first bit of the change:
https://bugs.webkit.org/attachment.cgi?id=185411&action=review

I expect most of the code from this feature to grow under these
CustomElementSomething and accompany classes.

Hope this answers your question.
