Issue description
Using index access on Quaternion data to get values will cause parsing errors; you can't access the x, y, z, w components of a Quaternion through indexing. However, similar types like Basis, Color, Transform2D, and VectorX can be accessed by index without any issues.
Please check the description in the game engine's documentation.
Steps to reproduce
Write the following statements in the script:
var q:Quaternion=Quaternion()
q[0]
