Constants, Aliases

[nazo]

Expressions! Expressions!  (/ ~.)/

I think that the exchange of parameters of alias is necessary from:
   alias (x*2) exp;
to:
   alias exp=x*2;

And I need alias arguments as syntax sugar like:
   alias(alias i) exp=i*2;
same as:
   template exp(alias i){
     alias exp=i*2;
   }
