Re: [PATCH] Suppress "Name used only once" warnings.

Turns out that it requires the latest IPC::Cmd (which I think is in blead already) and Locale::Maketext::Lexicon from CPAN. Then the warnings will show up with

    perl -Idist/Locale-Maketext/lib -Icpan/IPC-Cmd/lib -Idist/I18N-LangTags/lib -we "use IPC::Cmd"

I'm confused as to why Locale::Maketext::Simple, which bills itself as "a Simple interface to Locale::Maketext::Lexicon", is in core, but Locale::Maketext::Lexicon is not.

Best,

David
