in reply to Perl as interactive Shell?

The only reason Perl can be a replacement at all for the shell is because it can fork and exec. What it cannot replace is the shell's natural ability to communicate with itself. Rather than trying to solve all your problems with one tool, use the right tool for the task at hand.

Another way of looking at it is shell programming works on one level, and dynamic languages work on completely different level.

    Please elaborate "ability to communicate with itself" (?)

    Best with examples.°

    ... the rest sounds buzzwordy (and sorry also "sundial'ish" )

    °) I have the impression you don't know much about Perl's possibilities to communicate.

      Means you are trying to use shell in Perl when you should be using shell to use Perl: 
      curl -o - 'http://perlmonks.org/?node_id=1190142' | \
perl -Mojo -e'a("/"=>{text=>do{local$/;<STDIN>}})->start' daemon

        So using Perl in a REPL like the debugger is "VERBOTEN" ?

        I prefer facts over dogmas.
