Can't you get rid of it by removing the "" at the end (and thereby save an
additional 3 characters)?  I.e.,
	perl -ne'$,=$";print/(\b[A-Z]\w*)/g'

Depends on what your after? Efficiency comes in many guises (yes, I'm
kidding, sort of.. :-) Although I thought the usage of a temporary array to
store the words was pretty ugly as well! Anyway, I couldn't come up with
another, short piece of code to get the exact same print out as the original
piece of code. That is with out any extra white spaces...

Why, of course, how come I missed out on that! :-(

So if one was to combine all the best improvements so far one would get
(albeit with an extra white space at the end);

perl -ne'$,=$";print/(\b[A-Z]\w*)/g,""'

Looks pretty good! A part from the extra white space (yes, that bugs me for
some reason :-). Also I wish that the [A-Z]  part was internationalized
somehow.

So can it get even better? Or is that as fun as it gets? :-)
