Re: [Haskell-cafe] Insert a laziness break into strict ST

It seems that conversion from lazy to strict ST also removes laziness breaks. It seems that I have to stick to unsafeInterleaveIO, but I like to know, why the above method does not work. This isn't the answer you want, but there is an unsafeInterleaveST. This was a typo, I actually meant unsafeInterleaveST. So, I'm still uncertain why the conversion to lazy ST and back does not work. I feel, that I have still not understood what lazy ST actually means. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
