blanchet [Fri, 06 Mar 2009 19:37:31 +0100] rev 30314
Added "expect" option to Refute, like in Nitpick, that allows to write regression tests.
Also replaced calls to "Output.immediate_output" with "priority" or "tracing", because "immediate_output" causes some problems (as explained by Makarius to Sascha).

added lemmas

Fix remaining occurrences of "'a set" in Refute, by using "'a => bool" instead.
I tested the affected symbols (card, finite, lfp, and gfp), and Refute now works better than before (i.e., more precision and more speed).
