Comment on attachment 133191 [details] Patch How common are the invalid declarations? Is this worth making the grammar less readable?

Comment on attachment 133191 [details] Patch r- for now, I don't think this special case micro-optimization is worth removing the concept of 'property' from the grammar.

Ok Antti, I can re-write it slightly differently and keep property in the grammar but still defer the conversion. Will upload a patch shortly.

So this is a perf improvement? what's the speedup? (On which benchmark?)

(In reply to comment #13) > So this is a perf improvement? what's the speedup? (On which benchmark?) It might be a speed improvement, but only when parsing invalid declarations. Otherwise perf should be unchanged. Main reason is that: http://dev.w3.org/csswg/css-variables/ allows the definition of arbitrary property names that no longer map an integer, so having the property string available is useful.
