This is a live mirror of the Perl 5 development currently hosted at https://github.com/perl/perl5
add more tests to lib/mauve.t so it tests also that mauve::reftype can return "LVALUE"

18# NOTE!

20# Think carefully before adding tests here. In general this should be
21# used only for about three categories of tests:
22#
23# (1) tests that absolutely require 'use utf8', and since that in general
24# shouldn't be needed as the utf8 is being obsoleted, this should
25# have rather few tests. If you want to test Unicode and regexes,
26# you probably want to go to op/regexp or op/pat; if you want to test
27# split, go to op/split; pack, op/pack; appending or joining,
28# op/append or op/join, and so forth
29#
30# (2) tests that have to do with Unicode tokenizing (though it's likely
31# that all the other Unicode tests sprinkled around the t/**/*.t are
32# going to catch that)
33#
34# (3) complicated tests that simultaneously stress so many Unicode features
35# that deciding into which other test script the tests should go to
36# is hard -- maybe consider breaking up the complicated test
37#
