Used for insertion, traversal, and removal starting at a given item in the list.+A Node contains an immutable value of type a, and -s that point to the previous and next nodes.¢Node equality can be likened to pointer equality in C. Two Node values are considered equal if and only if they were created with the same insertion operation. if this is the list head.]List handle.

However, if you use < everything after that call will be executed everytime the  given to  is changed.You can also use the -$ instance to make a union of events.You can also use the . instance to run two things 'parallel'. Parallel meaning that events on one side will not cause the other side to be reevaluated completely.” is the portable Signal they can be exchanged between any parts of your program. Internally, they are just a variable and a list of change hooks./€the return value will remove the listener use 'fixm remover -> someListener remover' to add a listener that can remove itselfdoesn't really work yet€IO actions given here will be executed once a signal update has been completed. They keep the order in which they are inserted.@Runs everything below it everytime its input signal is updated.  Similar to v except that it also fires an event immediately, if the input signal is already initialized. It can be created using  and -This will evaluate the ¦ Monad. It will block until the first run reaches the end. After that, it will return the result and free everything. To prevent signals from reaching the end use  or  with some exit signal.0123456789:;/<=>?@AB :;/0123456789:;/<=>?@ABNoneCJust a synonym for C from -y. It basically prevents signals from ever progressing beyond this point. You can use this to make a filter for instance when (condition) stop Just for some quick debugging putLine = onCommit . putStrLn Returns immediately after registering the given computation. However, events from inside will not spread outside, except for the initial one.It is implemented like this 7local computation = return () <|> (computation >> stop) GGets the current value. Return Nothing if the signal is uninitialized. ÄCreates a new signal and gives you a way to update it. It is important to note that because the signal and the update function are separate, you can easily have readonly, writeonly permissions.
