I imagine they'll add map/filter/find after generics are in. It's pretty easy to define some slice types though which include those in the meantime, type Slice []string and add some functions then just use your new type for collections.

I suspect but do not know that multiple return values in a function combined with the inability to write functions against multiple return types like (T,error) will limit the usefulness of traditional iterators in Go. I'd love to be proved wrong as they'd really clean up my codebase though.

Depends what you're doing I guess, not everything needs to return an error, and errors can be accumulated and stored during certain operations and dealt with at the end.
