### Roblox - Property casing ### Roblox - Property casing
Today in Roblox, every index doubly works with camel case, such as `part.position` being equivalent to `part.Position`. This use is considered deprecated and frowned upon. However, even with variable renaming, this becomes significantly more appealing. For example, it is common you will only want a few pieces of informaiton from a `RaycastResult`, so you might be tempted to write: Today in Roblox, every index doubly works with camel case, such as `part.position` being equivalent to `part.Position`.

### Syntax for destructuring ### Syntax for destructuring
Many syntaxes have been proposed for destructuring. The most significant problem with any proposal is that is must be unambiguous to the reader whether or not the destructor is for **dictionaries** or for **arrays**.

An intuitive suggestion is `local { a, b } = t`, but this syntax fails this test--it is not obvious if this is `local a = t.a` or `local a = t[1]`, regardless of whatever syntax is chosen for array destructuring (should it exist).
