You can try the Perl debugger. For example:
Code:
$ perl -de 42
Loading DB routines from perl5db.pl version 1.32
Editor support available.
Enter h or `h h' for help, or `man perldebug' for more help.
main::(-e:1): 42
DB<1> print 4 + 5
9
DB<2> print "foo" if 4 == 5
DB<3> print "foo" if 4 == 2*2
foo
DB<4>

Not at all, the examples I gave are very basic, but you can try interactively almost anything you want, such as difficult syntax, hairy regular expressions, complicated data structures, etc.
