This is close to what you probably have in mind when saying "interactive Perl". Unfortunately, this one has some confusing behaviour with scopes, caused by the eval block: 

 perl> $_ = 'Foo'; print;
Foo
 perl> print;
print;

 perl> my $a = 'Bar'; print $a;
Bar
 perl> print $a;
Use of uninitialized value in print at (eval 4) line 1, <> line 4.

Writing the same commands in a file scoped script would produce different results.

I think it might be better to go this way:
Write a testscript in your favorite text editor. It might look like this:

#!perl            # header
use warnings;     # enable warnings
use diagnostics;  # explain warnings
                  # code to test:
print "Hey world, I'm coming!!!\n";

Then you can save the script (e.g. "C:\test.pl"). Open your DOS command window and type in the following to run your script:
perl C:\test.pl

When your script succeeds, you can modify it (trying out something else), save it and run the command again.

Hope this helps, have a lot of fun with Perl!
