    # returns either 'deutsch' or 'english'

The user's preferred language is taken from C<Glib::get_language_names> (see
L<Glib::Utils>).  If none of the given C<$lang> values are among the user's
preferences then the first in the call is used as the default and its
C<$value> returned.

This is meant for selecting semi-technical things from a fixed set of
possibilities within the program code, for example different URLs for the
English or German version of some web page which will be parsed.  If it was
in a F<.mo> file (per C<Locale::TextDomain>) the choice would be locked down
by the translator, but C<lang_select> allows a user preference.

lib/App/Chart/Glib/Ex/SignalBlock.pm  view on Meta::CPAN

instead use

    {
      my $blocker = App::Chart::Glib::Ex::SignalBlock->new ($obj,$id);
      ...
      # automatic signal_handler_unblock when $blocker out of scope
    }

SignalBlock holds weak references to the target objects, so the mere fact a
signal is blocked won't an object alive once nothing else cares if it lives
or dies.

=head1 OTHER NOTES

When there's multiple signals in a SignalBlock it's currently unspecified
what order the unblock calls are made.  (What would be good?  First-in
first-out, or a stack?)  You can create multiple SignalBlock objects and
arrange your blocks to destroyed them in a particular order if it matters.
