Again for the records, just to make things clear: Double-quoted strings 
in .po files are not the same as double-quoted Perl strings. Thus the 
Perl directive

	gettext ("%1\$s is replaced by %2\$s.");
	# Equivalent to:
	gettext ('%1$s is replaced by %2$s');

must result in

	msgid "%1$s is replaced by %2$s."
	msgstr "%2$s remplace %1$s."

in a .po file, because in Perl qq strings a literal dollar sign must be 
escaped, in .po files it must not be escaped.

Locale::gettext is really a subset of Locale::TextDomain/libintl-perl.

Yes and no: libintl-perl contains Locale::gettext_xs which is downwards 
compatible to Locale::gettext.  Locale::gettext_xs is exactly the same 
as Locale::gettext with bindings for the new GNU gettext functions 
ngettext() (and friends...) and bind_textdomain_codeset().

I rather would have extended Locale::gettext than introducing a new 
module (and a new namespace) but the original author of Locale::gettext 
was not available.  As soon as Locale::gettext is in sync again with GNU 
gettext, I would happily withdraw Locale::gettext_xs from libintl-perl. 
Alternatively Locale::gettext could be treated as obsolete.
