Minibuffer namespace

[hanche]

What new feature should Elvish have?

A separate namespace for use in the minibuffer

Make a namespace, say, $edit:minibuf:ns: that one can assign a namespace to. Name lookups in the minibuffer should check there first, followed if necessary by the usual interactive lookup. New variables created by var or fn should go in the interactive namespace as now. Thus the only way to alter the minibuffer namespace is to assign a new one to edit:minibuf:ns:.

Rationale

Commands made to be run in the minibuffer don't usually make sense elsewhere. This avoids polluting the interactive namespace with irrelevant commands.
