Influence of KRC and SASL on Haskell?

While learning Haskell I took a side road (so to speak) in researching the Kent Recursive Calculator and SASL functional languages. I was immediately struck by the similarities between them and Haskell and since they pr开发者_Go百科edate it I wonder if/how they provided influence.

Any information regarding the influence (or lack thereof) of KRC and SASL on Haskell would be much appreciated.

The connection you're probably looking for here is that David Turner, who was largely responsible for SASL and KRC, was also involved with Miranda, a non-strict, purely functional language. Miranda was relatively popular in its time, but was a proprietary language; an open standard alternative to Miranda was a major motivation for the creation of Haskell.

For further details, see also A History Of Haskell: Being Lazy With Class, by Hudak, Hughes, SPJ, and Wadler, which mentions Turner's work as well as other influences on Haskell.
