Re: Perl gurus: why do we need Scalar::Util?

Dear diary, on Mon, Jul 10, 2006 at 03:28:49PM CEST, I got a letter
where "Randal L. Schwartz" [off-list ref] said that...

While that syntax looks like it would make things easier in theory, in
practice it is a source of leak-after-leak because it creates a closure for
the two blocks, and that can easily lead to a circular reference for
long-running tools.

Care to elaborate, please? All I've found are several mentions that the
problem is there, but not what the problem actually is and it doesn't
occur to me why is it a problem.
