Meta: most reviews have the review dates in the Status field of their document,
this one doesn't. I was a little confused at first.
For the proposal itself:
# What is your evaluation of the proposal?
+1
# Is the problem being addressed significant enough to warrant a change to
Swift?
Yes, I write a lot of code just to initialize code. This will probably make
some of that code clearer.
# Does this proposal fit well with the feel and direction of Swift?
Probably?
# If you have you used other languages or libraries with a similar feature, how
do you feel that this proposal compares to those?
I frequently write C++ and Python and neither of them have it. This is
especially annoying for short programs.
# C# has an initializer syntax that allows you to assign properties at creation
time, and it is handy:
> Foo foo = new Foo() {
> Bar = "bar",
> Baz = 1,
> };
However, this pattern wouldn't be of much help in Swift, where most types don't
have a reasonable default value.
# How much effort did you put into your review? A glance, a quick reading, or
an in-depth study?
I followed the first week and a half of the proposal.
With all this said, I am confused with the way the proposal is written. The
Proposed Solution section talks about opt-in memberwise initialization with the
memberwise modifier on properties, but it is listed as a future direction and
the Detailed Design makes no mention of it. I would like to be clear that my
current appreciation of the proposal only extends to the Detailed Design, and
not necessarily to the future directions.
