 This theory defines the type inference rules and the type inference algorithm
 <em>W</em> for simply-typed lambda terms due to Milner. It proves the
 soundness and completeness of <em>W</em> w.r.t. to the rules. An optimized
-version <em>I</em> is shown equivalent to <em>W</em> (one direction only).
+version <em>I</em> is shown to implement <em>W</em>.
