Swift's rough approach to keywords is: </div><div><br></div><div>1) reuse contracted keywords that are widely known in the C family when the connotations are obvious (e.g. struct, enum, etc). </div><div>2) contract some “new” keywords for the *most commonly occurring* situations (e.g. func/var, though var is precedented in a number of extended c family languages like javascript), because people are expected to be forced to learn these things in the first few days of their swift learning.</div><div>3) otherwise, use a full word (subscript, convenience, mutating, etc).</div><div><br></div><div>In the case of subscript, it doesn’t occur often enough to be worth forcing people to memorize, and thus we prefer obvious clarity in the situations when it occurs in code.</div><div><br></div><div>-Chris</div><br></div> </div></body>
