Should EnvironmentRedirect call dispatch for removeAt?

[jamshark70]

EnvironmentRedirect help claims 'dispatch' is "A function or object that is called when the environment is modified."

However the behavior is inconsistent:

e = EnvironmentRedirect.new;

e.dispatch = { |... args| args.debug("e dispatch") };

e[\a] = 1;  // e dispatch: [ a, 1 ]

e.removeAt(\a)  // no post

At removeAt, the environment has been modified but the function was not called.

This could be resolved as follows:

	removeAt { arg key;
		var result = envir.removeAt(key);
		dispatch.value(key, nil);
		^result
	}

(One question is whether we would then need a localRemoveAt method mirroring localPut.)

I wonder whether the dispatch should be called also on clear.
