Yes, you can do that even now. IMO, this is a problem with the type of println. It should not accept functional values. I just sent a message to the nice-info mailing list about this.

Currently, you can write:

    let a = () => "hello";
    // these print "#<procedure gnu.expr.ModuleMethod>"
    println(a);
    println( () => "hello" );
    // these both print "hello"
    println(a());
    println( (() => "hello")() );

With the second kind of block call syntax, you could write:

    let a = { "hello" };
    // these print "#<procedure gnu.expr.ModuleMethod>"
    println(a);
    println( { "hello" } );
    // these both print "hello"
    println(a());
    println( { "hello" }() );

My proposal is that the type system should not allow the calls that print "#<procedure gnu.expr.ModuleMethod."
