Comment(by batterseapower):
Simon: yes. But now that I think about it, perhaps a more useful warning
is one that warns about ANY recursive pattern/variable binding? This would
help me find the class of bugs caused by accidental value-recursive
bindings in those situations that I need do. Those people who believe
silent letrec is a misfeature (there are some) could even turn it on for
their whole project and use "fix" to explicitly mark those places where
they really intend to use letrec.
