I thought I had said this earlier, but since I cannot find it, I will mention it possibly again: The implementations of equals vs. colon syntax for key-value pairs differ in that the latter requires a comma (or perhaps semicolon) between pairs, thus it does not need quote marks. Also, the equals sign is usually directly attached to the key and the (possibly quoted) value, without intervening whitespace, whereas the colon is almost always followed (and possibly preceded) by whitespace.
