The function is not referentially transparent: its type indicates that it is a pure function but it has the side effect of outputting the trace message.Like $ but returning unit in an arbitrary 74 context. Allows for convenient use in do-notation.Note that the application of  is not an action in the 7 context, as  is in the I type. While the fresh bindings in the following example will force the + expressions to be reduced every time the do-block is executed, traceM "not crashed"_ would only be reduced once, and the message would only be printed once. If your monad is in , traceIO may be a better option. T... = do x <- ... traceM $ "x: " ++ show x y <- ... traceM $ "y: " ++ show yLike  , but uses show$ on the argument to convert it to a String.This makes it convenient for printing the values of interesting variables or expressions inside a function. For example here we print the value of the variables x and z: Af x y = traceShow (x, z) $ result where z = ... ...Like  , but uses show$ on the argument to convert it to a String. D... = do x <- ... traceShowM $ x y <- ... traceShowM $ x + yThe s function outputs the trace message from the IO monad. This sequences the output with respect to other IO actions.
