Re: The distinction between "do BLOCK while COND" and "EXPR while COND" should go

*Only* do loops or do blocks in general?  And what should they do?

	do { ... last; ... };		# exit the block immediately
	do { ... next; ... };		# equivalent to last?
	do { ... redo; ... };		# equivalent to last?

These fall right in line with the proposal that the "do" be optional
since we can already do these:

	{ ... last; ... }
	{ ... next; ... }
	{ ... redo; ... }

And what about continue blocks?  We can attach them to bare blocks,
but not to do blocks?  That's weird.

Indeed.
