Re: Keys of a custom property array

URL is not a function. The reason why it's very often used with parentheses is because of evaluation ordering being unhelpful. There used to be a little popup in the old 1.1.1 documentation that explained operator order, and included containers and keywords. Consider these two statement: put U

Re: Keys of a custom property array

It seems there are two types of arrays storable in LC props, what I like to call "Natural" and "Unnatural": "Natural" arrays are one-dimensional, and fit into the traditional view of custom props as having one or more property sets, each of which is comprised of properties, each of which has a

I've run into other circumstances where using parens makes an expression yield the correct results. I can't think of them off the top of my head but the resukt has been that I probably use an overabundance of parens in my code so I don't have to worry about things working correctly. That's how I
