The simple examples are those that "use warnings" tells you about.
Perl::Critic  warned me about :
1.functions that don't return a value (but I don't think it checked if I
try to get the return value at the calling point at all)
2. no strict
3. no VERSION in a module
Etc.

They have different severities, so I can control how "carefull" I want
to be.
