<DIV><FONT face=Arial size=2>Hello, I have some code that manipulates STRefs
within the ST monad. All good and fine, until I come across some computation
that uses lets say IO and everything skids to a halt. At this point I have 3
choices:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. Define a ST State Transformer monad and do all
my previous ST computations in that</FONT></DIV>
<DIV><FONT face=Arial size=2>2. convert all subsequent ST computations into IO
computations using stToIO </FONT></DIV>
<DIV><FONT face=Arial size=2>3. stop using the ST monad and do everything in the
IO monad</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I was wondering what advice folks had. In
particular, what are the disadvantages to doing everything in the IO monad - ie
why even bother with the ST monad?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help appreciated</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
