Roblox added constants like Vector3.zero and CFrame.identity. These should be added to rbxmk.

List of constants:

• CFrame.identity = CFrame.new()
• Vector3.zero = Vector3.new()
• Vector3.one = Vector3.new(1, 1, 1)
• Vector3.xAxis = Vector3.new(1, 0, 0)
• Vector3.yAxis = Vector3.new(0, 1, 0)
• Vector3.zAxis = Vector3.new(0, 0, 1)
• Vector2.zero = Vector2.new()
• Vector2.one = Vector2.new(1, 1)
• Vector2.xAxis = Vector2.new(1, 0)
• Vector2.yAxis = Vector2.new(0, 1)

Implement by adding a Constants field to Reflector. This is similar to Constructors, but adds constant values instead.

Roblox seems to refer to these as "static" values.
