It’s not that strange. The statement contains an initializer (conceptually 'let
a = y.assocatedValue’), so there’s gonna be a “=“. Note that in your original
version:
> if case test.two( let a ) == y { }
what’s on the LHS of the “==“ isn’t a value of any kind — what were you
expecting the value of ‘a’ to be?
I get the same error with the for … in version. The compiler appears to be
treating x {…} as a closure, though I don’t know whether that’s cause or
effect. I vaguely recall Chris saying somewhere in the session that some things
weren’t implemented yet in the current compiler release. Maybe for case … in is
one of them?
