[perl #117607] TODO test for \&CORE::lc in error context

The original sample was:

BEGIN {
$^H |= 0x00000400; # strict vars
}
# Undeclared variable here
sub foo { return $anyvar; }
# Any CORE:: here
sub bar { \&CORE::lc }

simplified to:

BEGIN {
$^H |= 0x00000400; # strict vars
}
$anyvar;
&CORE::lc;

but it occurs for any compile-time error that doesn't abort compilation,
such as:

$foo/; \&CORE::lc
