in reply to Golf (Inspired): Repeated Phrases

I find this question unclear. Suppose that $m is 2 and $n is 3. Given that the phrase "this is strange" appears, do you want to see ("this is strange") returned or ("this is strange", "this is", "is strange")?

From both a programming and a spec problem I like only looking for phrases of a given size (which was what was done in the story). From that you can derive your solution through:

sub p{ ($m,$n,@_)=@_;map{f($_,@_)}$m..$n }
An incidental note. The mathematician in me reads your phrase "a list of" and wants to offer the following cheat as a "solution":
sub p{()}
(It is a list, and everything in it is a phrase of the right size that appears in both lists!)

And, of course, I can show that all golf can be improved with the utterly ridiculous:

sub p{}

    For sake of the golf problem, your example would return all 3 cases if m,n is 2,3. Extra credit for not including and/or removing phrases of x words that are part of phrases with y (y > x) words in the returned list.

    And the list must be of non-null words, so no trivial solutions :-)

[Corion]: Hi Lady_Aleena!
[Lady_Aleena]: marioroy, are you also writing a Meditation for this?

Lady_Aleena was checking #cbstream and saw the big announcement.
[marioroy]: Tie::IxHash can be shared. Also similar modules. I cannot wait to post a solution sharing Tie::File and iterating among workers.
[marioroy]: Lady_Aleena Yes, will post something with all the new features. Parallel with few lines of code.
[marioroy]: Yes, will do for PM. I love PM.
Lady_Aleena ponders a meditation of her own, but it would be on a far far less important topic.
[marioroy]: I'm hoping to have a release in about a week's time.
