... and then it's easy to imagine syntax like:

# Mumble to somevmod in every loaded instance
vmod.tell *::somevmod "mumble"

# Mumble to somevmod in the active instance
vmod.tell $$ACTIVE::somevmod "mumble"

Assuming that some string $$ACTIVE can be formed that may not be the
name of any VCL instance.

I doubt that we need somevcl::* or *::*, since it's unlikely that
there's a command that every VMOD's CLI will understand. Unless for some
reason we think of a command that any VMOD with a CLI should support,
which I guess is not out of the question after all. Think of something
like "give me back a version string for the VMOD".


Best,
Geoff
