If I have:

Code: Select all: class Test def a pass def b is shared .a()

I get the compilation error:

Code: Select all: error: Cannot access instance member "a" from the current shared member. Make the member "shared" or create an instance of the type.

Is there a way to call a private method from a shared method?

Sure, just make the member "shared" or create an instance of the type

By default, a method will be public. So, in this case the issue is that you don't have an instance of the Test class from which to call the a method as opposed to a being private. Check this out:

class Test
    def a
        print "a was called"

    def b is shared
        print "b was called"
        Test().a # we need an instance of 'Test' in order to call 'a'

class TestProgram

    def main
        """ 
        Prints...
        b was called
        a was called
        """
        Test.b

Makes sense?

While we're on the subject:

class A

    def thisIsPublic
        pass

    def _thisIsProtected
        pass

    def __thisIsPrivate
        pass

And you don't have to use underscores. You can use explicit declaration:

class A

    def thisIsPublic is public
        pass

    def thisIsProtected is protected
        pass

    def thisIsPrivate is private
        pass

Finally, the accessibility (public, protected, private, internal) is separate from the "level" (instance, shared).

That's the bit that I was missing in my understanding - I thought shared was synonymous with public. Thanks to both of you for the good explanations!
