Re: RFC 167 (v2) Simplify Cdo BLOCK Syntax

 One of the most common mistakes I make is forgetting a C; after
 Cdo BLOCK, probably because I'm thinking ``if'' and an if doesn't
 require a C: after it's closing C}.  I'll type, for example,
 
 $cond  and  do  {
 # statements
 }


Tom's already addressed the case where you drop the 'do' so, what
happens if you want:

$cond and do {...} or die;

Doesn't dropping the requirement for a terminating ';' make life
harder for the parser?

It doesn't seem like that's a criterion people have been applying
to any of this.  Unfortunately.

[Tom Christiansen]

Simpify syntax of Cdo BLOCK by deleting Cdo before the
block and C; after it.

You can't do that.  They do different things.

$n = do {
my $sum = 0;
for $i (@array) { $sum += $i }
$sum;
}; 

versus

$rec = {
FOO = 1.4,
BAR = "red",
};
