Wouldn't it be nice if there were a C level function that could be
called from a C level debugger like gdb and which would show the
*perl* statement (and filename, linenumber if known) being executed?
dump.c:Perl_op_dump() exists, but its output is not that nice to read,
use of B::Deparse might be useful (if available...)
Whether this function belongs in the core (dump.c?) or an extension
(B:: something, Devel::Peek?) I leave for others to discuss, but how
I can see this utility being used is:
$ gdb perl -e 'for(@a=0..99){pop @a}'
Segmentation violation ...
...
(gdb) call Perl_dump_where(...)
...
-e:1: pop @a;
...
