-%%---------------------------------------------------------------------
-%% This is added as a test because it was giving a false positive
-%% (function move/4 will nevr be called) due to the strange use of
-%% self-recursive fun construction in placex/3.
-%%
-%% The analysis was getting confused that the foldl call will never
-%% terminate (due to a wrong hard-coded type for foldl) and inferred
-%% that the remaining calls in the body of placex/3 will not be
-%% reached. Fixed 11 March 2005.
