I should probably also mock-up what it would look like when the target
node is at the top level.  With keyword after the node name:

/ {
	...
};
&some-node-to-remove /remove-node/;
&some-node-to-replace /remove-node/ { prop = "blah"; };

And with keywords preceeding:

/ {
	...
};
/remove-node/ &some-node-to-remove;
/remove-node/ &some-node-to-replace { prop = "blah"; };
