DOMString[] platforms = [];

I tried that but got an error in the v8 code generator at compile time. Any
ideas? This is the error:

Checking the spec and asking the editor, it's actually not possible to have
default values for dictionary :(

Please keep:
DOMString[] platforms;

[benwells, 2015/04/17 06:58:53]

Done.
