in reply to A minor epiphany with grep and map

By the way, I'm intersted in an examination of @$x->{y}. Examining the code generated with -Dx, I think this runs only by accident. The left side of -> is supposed to be a reference, but in that code, the left hand side is an array, namely, @$x. And it's not a syntax error to have one of those on the left side of ->{y} because of pseudohashes.

Or so it seems.
