Exploring parsing strings as variables.

@"\"Foo\" + \"Bar\"" would be equivalent to @"$Foo + $Bar"
@"'Foo' + 'Bar'" would be equivalent to @"$Foo + $Bar"
Numbers can now be entered as hex, beginning with either "0x" or "0X".

This does not interfere with the multiplication operator, because "x" is not recognized as multiplication; "*" and "×" (the actual unicode multiplication sign) are.
