Yes, I do admire this simple and clear code.
Choosing good names is an art and in terms of linguistic craft and agonizing over choosing good names, I claim that TimToady has no equal. :) As a former pacman player, I appreciate the (evocative) munch more than List::MoreUtils hard-to-pronounce natatime.
With functional-style languages, you need a lot of names, so choosing good and consistent names is crucial. Certainly, Haskell has a vast number of functions in its core library; related Haskell names here appear to be take, drop and splitAt from Data.List; more specific to the problem at hand, though not in core, is hackage Data.List.Split's splitEvery aka chunk. Does Perl 6 have equivalents to Haskell's take, drop, splitAt, splitEvery?
While salivating over munch, I hungrily searched for its documentation. Googling for "Perl 6 munch" left me unsatisfied, turning up only the Edvard Munch Museum tourist attraction in Oslo, among various IRC logs and blog entries, but no hits from the official Perl 6 docs. And I couldn't find it in S32-setting-library-Containers ... though I did find vaguely related Perl 6 names there, namely: shift, pop, splice, zip. Does anyone know where munch is officially documented?
Update: I just checked an online dictionary and it appears that munch and chomp mean almost the same thing:
chomp - To chew or bite on noisilyA mouthwatering challenge is to explain to a Perl 6 newbie how to remember which one does what. :)
munch - To chew or eat (food) audibly or with pleasure
