This is a bug report for perl from nick@ccl4.org,
generated with the help of perlbug 1.39 running under perl 5.13.3.


-----------------------------------------------------------------
[Please describe your issue here]

B::Deparse is getting the positioning of no overloading wrong:

$ ./perl -Ilib -MO=Deparse -e 'print; { no overloading; $a + $b}; print'
print $_;
no overloading;
{
    $a + $b;
}
print $_;
-e syntax OK
$ ./perl -Ilib -MO=Deparse -e 'print do { no overloading; $a + $b}; print'
no overloading;
print do {
    $a + $b
};
print $_;
-e syntax OK


In both cases, it should be inside the block.
I don't know if this bug just applies to the overloading pragma.
