By the last I assume mul() is meant; it may be best to spell that out

Which, on a more user-facing level, allows object-typed variables to be
used from within loops, and produces more optimized code for variables
accessed within loops in general.

A couple smaller things I noticed that I think are worth mentioning as well:
* The SV_VertexID semantic is supported.
* Matrix-typed varyings are supported.
