Allow final variables and final Fields (except blank final), to not having explicit Type.

Yes. Someone should work exactly this (and no more) into a separate
proposal, if it hasn't been done already.

Alternatives: "? foo" would sort of work since the "?" works, as a
wildcard, for some other type uses, but it is way too strange
looking. A new declare-and-assign operator would be nice for a wrist- friendly language, but IMO it is too different from existing Java
declaration syntaxes. Beyond subjective esthetics, consistency of
syntax is important to both mechanical and biological parsers.
Meanwhile, "final" variables avoid ambiguities about programmer
intention for additional assignments to mutable variables, so "final"
works with extra grace for auto-typed variables.
