Is there any way to get an explicit reference to a default provider instance inside a Pulumi program?

I haven’t found anything in the docs explicitly but I managed to get default provider (although I tested it on my custom ComponentResource where provider was overridden using

opts

):

gcp_provider = cast(gcp.Provider, self.get_provider("gcp::"))

That's handy inside a resource, but I haven't been able to track down how to grab a default provider from the top-level of a Pulumi program. Anybody else have any thoughts on this?
