unite-perl-module.vim is a plugin for unite.vim, which is a source for searching your installed CPAN module names.
It is inspired by rhysd/unite-ruby-require.vim.
Global Module List
Local Module List
It searches module in 'lib', 'extlib', 'local/perl5/lib' directories in your project.
The performance of unite-perl-module.vim may be slow when you are in directories with many child ones like HOME directory. This is because of the behavior of 'cpan -l', which is for listing up CPAN file. 'cpan -l' searches current directory recursively, so it may be slow. It's no problem if you are widtin a project directory.
