+True iff the module could have been built when thread-safety features.
+
+=head1 CAVEATS
+
+C<meth $obj> (no semicolon) at the end of a file won't be seen as an indirect object syntax, although it will as soon as there is another token before the end (as in C<meth $obj;> or C<meth $obj 1>).
+
+With 5.8 perls, the pragma does not propagate into C<eval STRING>.
+This is due to a shortcoming in the way perl handles the hints hash, which is addressed in perl 5.10.
