So now we can take an arbitrary number of parameters for msg? I thought that was
the reason for taking the dictionary so that we could ensure msg always too the
same one argument, but could be passed multiple different items inside.

If you are changing this, we need to change the example on line 58.

Yes, it can take an arbitrary number. I'm using Function.apply in the mechanism
using the "args" parameter. I think the original restriction was because we
didn't have that. The args and name parameters are currently mandatory, because
they're used in the runtime mechanism. That can change if we go beyond
generating additional code and start modifying the original, but right now that
doesn't happen. But they should also be in the examples.

sgtm.

should the return type here be a String?

[Alan Knight, 2013/03/14 17:49:05]

Oh yeah, right. Got so caught up in it having been turned into a Future I just
took it out and forgot to put String back.
