dear all,
it seems all the "lvalue sub" RFCs haven't mentioned this.
currently we can do
$str = "foo bar";
substr($str, 4, 0) = "baz ";
and $str will become "foo baz bar". should we be able to do
this with lvalue-subs? how can one returns "pointer" to a
portion of a scalar?

dear all,
today this just came up to my mind, we could have a pragma that disable
`autovivification' of hash and array keys. Consider the follow code snippet:
@arr = ( 0..9 );
%hash = ( a=1, b=2 );
{
no autovivify;
$arr{10}++; # both are
$hash{c}--; # fatal
}
this way
