   At positive type we have

   In denotational semantics, positive types behave well with respect to “call-by-value” and other eager evaluation strategies.

   and dually at negative type we have

   In denotational semantics, negative types behave well with respect to “call-by-name” and other lazy evaluation strategies.

   This doesn’t seem right to me; don’t evaluation strategies belong to operational semantics?

   Format: MarkdownItexHmm, [this CST.SE answer](https://cstheory.stackexchange.com/a/32581/28847) suggests that maybe evaluation strategies are considered part of denotational semantics insofar as they affect the *end result* of a computation rather than the implementation details of how that result is arrived at.
