*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.
