URI::URL query vs equery

I'm testing a module using URI::URL, and it refuses to call query() on
the URL created by google (lines should be merged...):

The error message is

Form query contains escaped '=' or '&' (you must call equery)

Of course, equery() works; however, I would prefer to have the result
of query()... Can somebody explain the reason behind this madness?
How to avoid this?

Thanks,
Ilya

Backwards compatiblity.

Avoid URI::URL; use URI.pm instead.

That would be good. But is the error message backward-compatible???

How? AFAIU, it has no analogue of query()...

Thanks,
Ilya

P.S. I do not care if query() is lossy...

Not really sure. I hope so. I don't have any old versions of
URI::URL laying around so I can't easily check.

I would think that query_form() would be the right method for decoding
this URL. The old query() is gone because I strongly believe it was a
bad interface.

Then you could use:

uri_unescape($u->query);

or if you really want to stay with $u as a URI::URL reference:

uri_unescape($u->equery);

Can you please be more specific? This is is what $u->query() does if
it would not die() in the check above... Was there any reason for the
check, or was it just a pilot error? Apparently, google has no
problem with URL above...

(query_form() returns pairs; I'm not interested in pairs...)

Thanks,
Ilya

P.S. During last two years I sent some email to you, and do not
remember seeing answers. I know some bugs/problems in LWP, is
it possible to report them without subscribing to yet more
mailing lists? E.g., is the news server mirror back-propagated
into the mailing list?
