5// If you compile with strict mode and specify a different casing like "Pass" instead in an identifier, FXC will give this error:
6// "error X3086: alternate cases for 'pass' are deprecated in strict mode"
7// This behavior is not documented anywhere, but as far as I can tell this is the full list.
