What are the disadvantages of using a Perl debugger and a real REPL like Devel :: REPL?

I usually use perl -de 42 to get the Perl interactive shell. I saw Devel :: REPL and I saw some blogs, such as http://www.xenoterracide.com/2010/07/making-repl-usable.html , explaining how you can improve Devel::REPL with plugins but I haven't used it yet.

Is it too bad to use the debugger as an interactive shell? Why?

Note: The flaws mentioned in this PerlMonks node were limitations of the user, not the Perl debugger.

Where can I learn more about Perl REPL?

Is Devel :: REPL ready for the spotlight?

UPDATE: I accepted Pedro's answer because he answered the question I asked, but still I would like to know when and why (if any) using the Perl debugger as an interactive shell is a bad idea compared to one of the Perl implementations REPL, And which Perl REPL do you prefer?

One of the drawbacks of perl -d is that lexical variables immediately go beyond the scope. Example:

 DB<1> my $p = 123; DB<2> print $p; DB<3>

From perldebug :

Note that the specified eval is bound to implicit volume. As a result, a lexical variable or any modified contents of the capture buffer lost after evaluation is introduced. A debugger is a good environment for learning Perl, but if you are experimenting interactively using material that should be in the same volume, material in one linear object, write it on one line.

Instead of using a debugger and skipping functions, I usually use only

 perl -wnE'say eval()// $@ '

I used Devel :: REPL and something like this, but just not used to using it.

The advantage of using a debugger is that $DB::single=1 can also stop one-step at a given point.

Both have different goals. The debugger is optimized to debug an already written Perl script / program. While the main objective of REPL is to provide fast language feedback and optimization for interactive input (developers).

For example, if I do the following in the Perl debugger:

 DB<1> for my $x (1..10) {

I get the error Missing right curly or square bracket at (eval 5)...

While Devel::REPL allows you to use multiple lines:

 $ for my $x (1..3) { > say $x; > } 1 2 3

I fully recommend Devel::REPL , and with additional plugins it will become a convenient development tool that will work next to your editor.
