It contributes to the notion of perl being obscure and hard to read.For me, it contributes also to the notion that perl is hard to write - summing both: that perl is very sophisticated.
I like golf not only because it reveals dark corners of perl; it also reveals perl's tremendous ability to eliminate noise and produce dense expressions. Ultimately, golf tends to be noise, when shorter statement can not anymore be contrieved, but even those constructs - add a bit of air (white space) to them, a bit more verbosity, and many of them expand into beautiful, perfectly understandable nailing-downs of solutions to the problem at hand.
which is a common idiom in many languages, to
of which the latter is the golfed code version, useable in production code, and you must admit that perl to some extent is golf - well, compared to Java anyways ;-)
Any language is "obscure and hard to read" for those that don't venture into it; and no matter whether that "obscure and hard to read" judgement is uttered as a pretext to not do so, or as a disinformed dismissive, it is just prejudice - and there being perl golf or not doesn't change that in the least.
