Function literal with multiple implicit arguments

Question

How to define function literal with multiple implicit arguments in Scala? I\'ve tried this way:

def create = authAction { (implicit request, user) ⇒ // Synta

Just had a similar situation as you, implementing an authAction function in Play that would easily pass a user in. You can do it like lambdas did it, with currying; I ended up making my authAction function receive the RequestHeader implicitly, but pass in both request and user explicitly:

def authAction(f: (RequestHeader, User) => Result)(implicit request: RequestHeader) = {
    ...
    val authUser = loadUser(...)
    f(request, authUser)
}

And to use it:

def create = authAction { (request, user) =>
    Ok(html.user.create(registrationForm))
}
