334rarely a good idea.

553
554All coderefs in this array will be called as methods of the next newly
555created C<urxvt::term> object (during the C<on_init> phase). The array
556gets cleared before the codereferences that were in it are being executed,
557so coderefs can push themselves onto it again if they so desire.
558
559This complements to the perl-eval commandline option, but gets executed
560first.
561
562=item @urxvt::TERM_EXT
563
564Works similar to C<@TERM_INIT>, but contains perl package/class names, which
565get registered as normal extensions after calling the hooks in C<@TERM_INIT>
566but before other extensions. Gets cleared just like C<@TERM_INIT>.
