It s generally thought to be bad style to combine delayed computations (that is, laziness) and side effects. This isn t entirely true; for example, it s reasonable to set up a read from a file system as a lazy computation using sequences. However, it s relatively easy to make mistakes in this sort of programming. For example, consider the following code: open System.IO let reader1, reader2 = let reader = new StreamReader(File.OpenRead("test.txt")) let firstReader() = reader.ReadLine() let secondReader() = reader.ReadLine() // Note: we close the stream reader here! // But we are returning function values which use the reader // This is very bad! reader.Close() firstReader, secondReader // Note: stream reader is now closed! The next line will fail! let firstLine = reader1() let secondLine = reader2() firstLine, secondLine This code is wrong because the StreamReader object reader is used after the point indicated by the comment. The returned function values are then called, and they try to read from the captured variable reader. Function values are just one example of delayed computations: other examples are lazy values, sequences, and any objects that perform computations on demand.
