Advice on referencing external values about json-swift

[paulyoung]

Similarly (but not involving enum), this:

let foo = [
    "bar"
]

let dictionary: JSON = [
    "foo": foo
]

Results in:
Dictionary<$T3, $T4>' is not convertible to 'JSON'

Perfectly reasonable... but Swift doesn't allow implicit type conversion. Since those are not literals, they cannot be converted.

A couple of options:

let foo: JSValue = [
    "bar"
]

let dictionary: JSON = [
    "foo": foo
]

Or:

var array = [JSValue]()
array.append("Item #1")

var json = JSValue(array)

What about raw enum values?

[owensd]

let array: JSON = [
    JSValue(Foo.Bar.toRaw())
]

[owensd]

Pre-beta 6 there was a __conversion() override we could implement; this allowed converting Strings, Ints, etc... implicitly. That is now removed so when you deal with instances of types, you need to box them into a JSValue.

It sucks.

Good enough for me. Thanks!
