<obj> Foo á-> gives binding of 'Foo' in environment.
<obj> Foo: <value> -> sets the new value.

One of the goals with environments is to avoid syntactic or semantic changes to the language. All existing code should run as-is, and still benefit from the namespace isolation that we get from environments. Your idea above seems feasible for a new language, but it breaks compatibility.

So I'll take this as a vote in favour of Eliot's ideaŚmessage send rather than direct access, but preserving the existing syntax and semantics of Smalltalk.á
