[swift-users] still wrestling with a type conversion problem

Auggh! I only thought it worked.  Luckily, I had help.  My 16 year-old son looked at this code, and *he* figured it out:  I meant to write
   
>     if  let dt = T.self as? DecodableFromAny {

as

     if  let dt = T.self as? DecodableFromAny.Type {



Now, I swear, it really does work.
