Here's my list

byte size integral literals either via autosizing hex literals 0hNNNN 
(type is smallest type that can hold the value - would probably also 
include binaries 0bNNNNN) or alternatively via a new integer literal 
suffix (would include shorts as well).

A zero fill (unsigned) widening conversion (but can't call it that cause 
we lose sign) / operator probably "(+)"  to morph bytes into integers 
without sign extension.

A special language escape operator which will always generate a compiler 
error. Reasons too complex to explain in one sentence. - no 
implementation required.

Maybe: Type literals (for annotations) depending on where the field / 
method literals discussion goes - might be too big for coin.
