Wouldn't it be possible to generate the code by code generators? (Some change might be needed in CodeGeneratorV8.pm though.)

webkitLineDashAccessorSetter and webkitLineDashAccessorGetter are just setting/getting values to/from Arrays, which I think should be generated by code generators.

The original problem, as I recall, is that it uses non-standard type 'DashArray' to hold the values. But let me check how it can be done in CodeGeneratorV8.pm, thanks for your suggestion.

Has there been any progress on this?

The standard lineDash feature will make webkitLineDash obsolete.
