in thread recursive anonymous subroutines

How would one do that? I'm curious.

    OK, I found a way, but you won't like it! :-)
    Use $DB::sub->() but you have to run it under the perl debuger (perl -d):
    sub { print 'A'; $DB::sub->() }->();

    Ted Young

    ($$<<$$=>$$<=>$$<=$$>>$$) always returns 1. :-)

      That only works when the debugger is enabled. For general use, see Devel::Caller.

    I'd write a little very scary, very hairy XS code. I don't know which of three or four approaches would work best, but I'd start by poking around PL_curcop.

      Surely the *best* approach is to not write the scary hairy XS code and just accept that you'll have to use a variable. It's not like variables kill babies or anything.
