Parenscript and implicit Return

Question

Is there anyway to turn off Parenscript's implicit Return?

I'm trying to write the following code:

function () = { dialog.show();};

But Parenscript inserts an implicit return:

(ps (lambda ()
      (chain dialog (show))))

=>

function () = { return dialog.show();};

Answer 1

No. (CoffeeScript works the same way, too.) This is a feature, not a bug. Explicitly return undefined if you really care.

Answer 2

You could use (values):

(ps (lambda ()
      (chain dialog (show))
      (values)))

This should probably return undefined (but it actually returns null). If you really need undefined, you have it:

(ps (lambda ()
      (chain dialog (show))
      undefined))
