I found a problem trying to get s value directly from a quaternion q.
Compiling a script which directly access to q.s value, caused the
following error:
CS0103: 'The . symbol cannot be used in LSL except in float values
or vector components'. Detected around: q.s
I did a small change to allow alphabetic letter "s" to be interpretated
as valid identifier. This solves the problem.
