It’s the equivalent of trying to construct a struct value with non-optional properties, but without providing any init parameters, it would result in an invalid value. If your proposal were possible I think it would cause trouble with pattern matching enums too. In a switch statement that expects to bind to associated values, what happens when it receives an enum that should have associated values, but they are not present?</div><div class=""><br class=""></div><br class=""><div><blockquote type="cite" class=""><div class="">On 11 Dec 2015, at 04:53, Evan Maloney <<a href="mailto:emaloney@gilt.com" class="">emaloney@gilt.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">You're referring to the ability to test whether an existing enum value is of a given case regardless of the contents of its associated values.
