@rosenfeld, I'll just mention that you can use Proc#[] in your example:

double = -> n { n * 2 }

double[3] == 6  #=> true

I propose for the parser to interpret &quot;object(...)&quot; as &quot;obje=
ct.call(...)&quot;. It should raise NoMethodError at runtime if object does=
n&#39;t respond to &quot;call&quot;.<br>
<br>
This would read better than using &quot;call&quot;:<br>
<br>
double =3D -&gt; n { n * 2 }<br>
<br>
double(3) =3D=3D 6<br>
<br>
Sorry if this has already been proposed before (and rejected) but I couldn&=
#39;t find any references to something like this using Redmine&#39;s search=
 interface.<br>
