So what proposals are still fermenting in the minds of coin contributors? Inspired by the recent discussion between Joe D'Arcy and Mark Mahieu that people are possibly thinking someone else will be proposing it.

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.
