Classes *are* libraries. Methods *are* functions.
A class is simply a module that contains one or more subroutines which
function as methods.
A method is simply a function that expects either a class name or
blessed reference as its first argument.
What he said was correct. What you said was simply more specific.

1) that's a compilation error, not a warning. What was it you said
about a pedantic level of detail?
2) That error will only be displayed if the OP is using strictures.
Nothing in his post indicates that he is.

This is nonsensical. ALL subroutines in perl are passed by
reference. I think you meant "You do not need to pass a reference to
it", which is remarkably different. There's that less than pedantic
attention to detail again...
