asserting a dyn to a map type

[Dan Kortschak]

I have a situation where the activation is a dyn, but in some cases I
know that it is a <map<string,dyn>>. I have extensions that overload on
the known type and walk into the map with a path, and cannot use the
dyn type (this could be relaxed, but I would rather not just for this).
Is there a way to assert/coerce with potential of failure to the map
type? I don't see this anywhere.

What I am able to do instead of `val.walk("a.b.c")` is `{"val":
val}.walk("val.a.b.c")` which does work. Am I missing something?

thanks
Dan

Hi Dan,

There are no map() type assertions, but you could write `type(val) == map ? val.walk("...") : {"val": val}.walk("...")`

I'm not sure if that helps, but maybe so.

Thanks, Tristan. Clarification always helps.
