Meaning of Life (Hitchhiker`s Guide to the Galaxy)

As you might know, the answer to the ultimate question is 42, according to [http://en.wikipedia.org/wiki/Douglas_adams Douglas Adamss] famous book "[http://en.wikipedia.org/wiki/The_Hitchhiker's_Guide_to_the_Galaxy Hitchhikers Guide to the Galaxy"]. We do not need a supercomputer and millions of years to proof that. Whatever you specify as right argument to this function:

MeaningOfLife←{+.×/⍎⊖⍕⊃¨⊂|⌊-*+○⌈∨.∧/>\</×÷!⌽⍉⍉⌹~⍴⍋⍒,⍟?⍳''≡1↑0⍴∊⍵}

...will produce a reasonable answer, regardless which type/lenght/depth/rank it is.
