in reply to Script/module formatting gotcha

As jettero pointed out, it's an rvalue assignment - and although the code in the example that you cite isn't doing anything worthwhile, the mechanism itself is a perfectly valid and useful one. Without it, you couldn't do things like

die "Syntax: [...]\n" unless my $fname = shift;

and so on. I think that the right perspective here is that the tools are available and usable, but the decision about whether something is useful or not is up to the human. :)

    Understood, and I have no problem with the rvalue itself being an lvalue (if that makes sense).

    My only point here was that splitting this construct across multiple lines, with a large number of comments in-between, makes the script difficult to read - the construct itself is clear, and useful :)
