You can certainly use thread but in most use cases, concurrency or
parallelism will accomplish the same in a much saner/safer way. (they're
wrappers around core.thread anyway).
Don't know of any tutorials about core.thread, about the other two you can
find help here : http://ddili.org/ders/d.en/

Thank you for all answers.
Removing typeof do resolve the problem when the second parameter

However when passing an array of string the error still occur:
