: IMO, all of these are worse than "label:". And most of your syntaxes
: limit labels to blocks, while currently they can be placed before any
: statement, and it has been said that this behaviour is preferred.
Labels will remain on statements. However, you can sneak a statement
(including its label) into the middle of an expression by using "do":
$outer = do LINE: for =$IN {...; $inner ==> leave LINE }
Note that "do" no longer requires braces unless you wish to continue the
expression after the do. Which we can get away with because do-SUB
is gone and do-File is renamed to evalfile or some such. Maybe it
can be demoted to
eval requirefinder($filename);
since we're trying to discourage use of do-File anyway, and we can probably
abstract out the parts that require and do-File have in common.
