Can't instantiate r-value ModuleReferences

[kwikius]

ar = [ module cube(10)];
m = ar[0];
m();  // ok instantiate cube
ar[0]();  // syntax error

Currently the workaround is to create an l-value ( e.g a name to assign the module_reference) and instantiate that as shown above.
Allowing instantiation of r-values will require mods to the parser

One syntax which works is to wrap the expression in brackets

ar = [ module cube(10)];
(ar[0])();  // 

ar1 = [ module cube];
(ar1[0])(10);  // showing args to instantiation

Parser.y is modified to

instantiation_expr
     : module_id
       { $$ = $1;}
     | '(' expr ')'
           { $$ = $2;}
      ;

single_module_instantiation
        : instantiation_expr '(' arguments ')'
            {
                $$ = new ModuleInstantiation($1, *$3, LOCD("modulecall", @$));
                free($1);
                delete $3;
            }
        ;
