Applications using the perl IO:Compress package will warn about incorrect use of the length function in IO::Compress::Zlib::Extra Reproducible: Always Steps to Reproduce: 1.Run a program using IO:Compress under perl 5.16 2. 3. Expected Results: No warning messages Warning message from perl 5.16: length() used on @array (did you mean "scalar(@array)"?) at /usr/lib/perl5/vendor_perl/5.16.0/IO/Compress/Zlib/Extra.pm line 166.
Don't use testing dev-lang/perl and stable perl-core/ packages. It doesn't work reliably.
But I've ended up here becuase autounmask thinks that perl-5.16 is needed by Test-Simple and Ima-DBI: #required by virtual/perl-Test-Simple-0.980.0-r2, required by dev-perl/Ima-DBI-0.350.0, required by @selected, required by @world (argument) =dev-lang/perl-5.16.0 ~x86 I don't know how to avoid the upgrade if Test-Simple thinks 5.16 is needed...
