A few interesting excerpts from the docs:

|The default value if none is specified is threshold 1.0.

|Conditional expressions: The operand C is boolean while operands A and B 
|are any expressions. The result is of the same type as A and B.
|
|(C ? A : B)         if C then A else B

|You may use the dot operator to extract a single float component from a 
|vector. Suppose the identifier Spot was previously defined as a vector. 
|Then Spot.x is a float value that is the first component of this x, y, z 
|vector. Similarly Spot.y and Spot.z reference the 2nd and 3rd components.
