The magic 8-ball says:

Make ill.pm return a true value.


perldiag:

       %s did not return a true value
           (F) A required (or used) file must return a true value
           to indicate that it compiled correctly and ran its
           initialization code correctly.  It's traditional to
           end such a file with a "1;", though any true value
           would do.  See the require entry in the perlfunc
           manpage.

P.S.  By convention, a module's name should start with a capital letter,
unless it's a pragma.

P.P.S.  'use diagnostics;' is often a useful pragma.
