Why do you need the asInstanceOf(), when name is already declared to be a String?
Sorry if this is obvious; I don't know Scala (I've glanced at it, but the 2.8 compiler is too slow on my laptop--as in, about one line per minute).
- rit 16y agoSorry, you don't. It's a leftover from an earlier attempt to do something different with dynamic. Your assumption is correct: It is already a string and there is no purpose to casting it to a String. I don't recall exactly where that artifact came from but I recall the original release of Dynamic had a very different method signature and I was fiddling to figure out the new signatures when I wrote this. The examples I found when I wrote this used the old interface and the new one had no docs or examples yet so I did a bit of playing. I've updated the gist to remove the unnecessary asInstanceOf and demonstrate it as proper code.
- metageek 16y agoAh, nice. Thanks for answering.
