In this way it is easier to understand that F is the function itself within the definition. Also, Foo and F can be the same variable. This is Learn You Some Erlang for great good! This book is for you if you’ve got some programming experience and if you’re not too familiar with functional programming. It can still be useful if you’re too good for that, as we progressively go into more and more advanced topics. '>>='(X, Fun) -> Fun(X). return(X) -> X. fail(X) -> throw({error, X}).
