in thread Distinguish between missing and undefined arguments with subroutine signatures

If you are talking about compile-time checking ...

No, I'm not talking about compile-time checking. I want method call checking at runtime. My sig_lexical example does what I want, but I'm not sure if this is a legal usage.

    I can't follow anymore.

    You want 1 argument for a setter, and 0 arguments for a getter.

    Hence you need a conditional check anyway.

    So use a @slurpy parameter and check the size at runtime.

    Then die "too many arguments" if @slurpy > 1

    Problem solved.
