Yak, this example is a horrible one, since force-output doesn't return the return value of the procedure anyway, but if you try replacing it with (lambda () (throw 'wontthrow)), and you'll see it doesn't error In sf_flush in libguile/vports.c, there is a test if (pt->write_pos > pt->write_buf) which some printf debugging tells me is never true, in fact, those values never change, no matter how much I write to the port. Some food for thought while I grapple with how the ports code is supposed to work. -- Ian Price "Programming is like pinball.
