t/lib/warnings/op: recently added TODO-ed test

The test below was added by Dave Mitchell over the weekend to 
t/lib/warnings/op.  (Specifically, as part of commit db18005b269.)

I'm wondering what it will take to un-TODO it.

#####
+# TODO PL_curcop restored correctly in Perl_scalar()
+use warnings;
+my $scalar = do {
+    my $x = 1;
+    11,12,
+    do {
+        no warnings 'void';
+        my $x = 2;
+        21,22,
+    },
+    31,32,
+    do {
+        my $x = 3;
+        41,42,
+    },
+    51,52
+};
+EXPECT
+Useless use of a constant (11) in void context at - line 5.
+Useless use of a constant (12) in void context at - line 5.
+Useless use of a constant (31) in void context at - line 11.

Thank you very much.
