Re: Nested calls in make

[Boris Godin]

The make tries to expand the function (which in this case is infinite), that's why you can't see any output.
But... what are you trying to do? You should be more specific.

Yep, that's the correct behavior.  Apparently that's not what you
expected from the text.  It would be easier to correct your
understanding if you were to explain how you thought that snippet
would behave.
