in thread Short and easy way to write if...elsif syntax

The “clever improvements” as suggested cause each of the various if cases to become coupled.

(Some annoying typography elided.) How so—especially in the given/when case?

    Given/When is syntactic sugar for if..elsif.

      Perhaps I'm misunderstanding what you're saying, but given is a topicalizer, aliasing a lexically scoped $_ to a scalar's value which when operates on. The if/elsif construct doesn't create topics. Given this difference in functionality, how is given/when syntactic sugar for if/elsif?
