yes but probably not in a sense that you expect it. the perl debugger can be
involved to work like an interactive Perl environment:
[panda]# perl -de 1
... [snip a few lines] ...
main::(-e:1): 1
DB<1>
at the DB<1> prompt, you can eneter anything you want. if it's not
recognized by the debugger, it's passed directly to eval so you can do
stuff like:
DB<1> print "hello world\n"
hello world
DB<3> use strict;
DB<4> use warnings;
DB<5> sub sum{ \
cont: my $sum = 0; \
cont: $sum += $_ for(@_); \
cont: $sum; }
DB<6> print sum(1..5),"\n";
15
DB<7> q
[panda]#
'q' will exit the debugger. lines ends with '\' signal the debugger to grab
the next line. it's a little unusually to use the debugger for an
interactive Perl session but it's capable of doing it.
