interestingly enough, I used something (partly, at least) similar in a recent post of mine.
in my endless quest for Evil Things To Do, I was looking for a way to express this: in a more succint way. the first thing, of course, was to get rid of $ref, and so I wrote: but this is nothing sexy. so I thought, maybe I can get rid of $ref while still retaining the shift: but this doesn't work, and it took me a bit (and the help of B::Deparse) to understand why. ${shift} is interpreted by the parser as a way to write $shift, and of course it returns nothing. so I realized that the Perl parser needs to be hinted to get shift as a keyword, and this can be done in (at least :-) 3 ways: the last one I find particularly surprising :-)
