The thing is, I want to be able to control my error messages. Right now, I have
#The error I get: #C:\thomasdata\experiments>perl unblessedWantBetterError.t #Can't call method "isa" on unblessed reference at unblessedWantBetter +Error.t lin #e 10.
It is an error message, but it comes from the compiler, not from me. My main problem with it is isn't so much the wording, but the fact that it doesn't even say which argument caused the problem. Maybe params validate solves that?

That said, I am overall not currently happy with how I'm going about params checking. I will have a look at Params::Validate like diotalevi said, and maybe give my whole way of doing this a rethink.
