Hi List,<div><br></div><div>I&#39;ve recently had a situation where I used the same pattern quite a bit  while reducing and evaluating an AST. I quickly wrapped the operation in a package and stuck it on github.</div><div>
<br></div><div><a href="http://github.com/sw17ch/rebox/blob/master/src/Data/Rebox.hs">http://github.com/sw17ch/rebox/blob/master/src/Data/Rebox.hs</a></div><div><br></div><div>I&#39;m wondering two things:</div><div>1) Does any one recognize the pattern I&#39;m using here as something with a different name?</div>
<div>2) Is this worth sticking on Hackage? It&#39;s trivial, but we have plenty of trivial concepts on Hackage (and it&#39;s not a bad thing).</div><div><br></div><div>Any feedback would be great.</div><div><br></div><div>
