It would appear that 5.6.1 does behave a little differently to 5.6.0 in
respect to lvalued AUTOLOAD. Consider:
my $foo = 42;
sub foo :lvalue { $foo }
sub AUTOLOAD :lvalue { goto &foo }
bar() = 4711 if $ARGV[0] eq 'run-time';
With 5.6.0, this compiles and runs, unless you give an argument of
`run-time' in which case it croaks with:
Can't modify non-lvalue subroutine call at /tmp/goto line 4.
5.6.1 on the other hand dies at *complile-time* (ie. irregardless of
the argument) with:
Can't modify goto in lvalue subroutine return at /tmp/goto line 3, near "&foo
}"
Execution of /tmp/goto aborted due to compilation errors.
