they can be directly executed with various kinds of interfaces. Values
and interfaces are <i>combined</i> for direct use, and <i>separable</i> for composition.<br><br><a style="font-weight: bold;" href="http://haskell.org/haskellwiki/GuiTV" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

up to version 0.1.1. I moved it out to a new package to eliminate the
dependency of core TV on Phooey and hence on wxHaskell, as the latter
can be difficult to install.<br><br>See this <a href="http://conal-elliott.blogspot.com/2007/02/separating-io-from-logic-example.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">blog post</a> about for an example of using TV to neatly separate logic from IO.
