To my understanding the real reason why this is currently not possible is 
rooted in the limitations of struct Mirror, which, for instance, lacks the 
support for writing and the reflection of methods.

So it boils down to the following: Are there currently any plans to extend the 
capabilities of struct Mirror to support better reflection?


Trying to answer this question I found this post: 

https://lists.swift.org/pipermail/swift-users/Week-of-Mon-20151214/000512.html

where Joe Groff says there is something planned.


Are there any news on this, maybe a rough timeframe or Swift version for which 
to expect better reflection support?


Thanks,

        Lars
