Not at all, use it for whatever you want to :-)<br>

I'm writing this code because I'm preparing to write a bunch of tutorials on FRP, and I first wanted to start with simple console based FRP, e.g. making a little text adventure game, where the input/choices of the user might be parsed ala parsec, using monadic style, applicative style, and arrows, and then doing the same with FRP frameworks like <br>

This is a really bad place to start a FRP tutorial IMO.<br>
<br>
The interface for 'interact' does not make any promises about the relative evaluation order of the input list / production order of the output list.<br>
<br>
That's why you are having to play horrible tricks with seq to try to force the order to be what you want.<br>
<br>
I don't think this is the basis of a robust system or a sensible tutorial.<br>

Just my 2c.<br>
