RawValue for optional value

[Kyle-Ye]

The rawValue implementation is call description method

case .constant(let value): return "\(value)"
default: return ""
}

So if a TemplateValue's Value is an Optional type, it's result will surprisingly be "Optional(xx)"

A example is the following

id is UUID? type and a property in Post model
post is TemplateValue<Post> here

A { "Hello" }.id(post.id.rawValue)

This will give me "Optional(xx)" or "nil".
But what I want is "xx" or "".
However I can't do it, since I can not get a Post type or UUID? here.
All I can get is TemplateValue<Post> and TemplateValue<UUID?> and then call the rawValue method.

A potential solution is to support for..in loop directly in result Builder. See #72

So that we can write

Tbody {
    for post in posts {
        Tr {
           H1 { post.title }.id(post.id?.uuidString ?? "")
        }
    }
}

Not sure, what you trying to do. But the native statements are not possible at the moment. The same as we have discussed in the issue #61.

Would the statements Unwrap and Foreach help in your case?

Got it, Unwrap is what I need. Thanks
