Re: query type of an instance

You can just call the class() method on objects. Somewhere near the top of your source file:

(define-namespace Object <java.lang.Object>)

... and then, when you want the class of foo:

(Object:class foo)

You mean of course the getClass method:


(Object:getClass foo)

You can also just write:
(foo:getClass)

However, that requires that foo not be a Type or Class
name, since in that case Kawa looks for a static method.

There is a "class" property, because Kawa implements
the JavaBeans conventions that a field "bar" is
equivalent to a method "getBar".

I.e. (as Yaroslav found out):

foo:class

Not really.  Syntax hygiene makes that somewhat tricky.
Luis's macros seems useful as a start.

If I had time I'd like to re-write Kawa's macro-expander
to make it fully compatible with R6RS, probably based on
André van Tonder's code.
