[Haskell-cafe] Pattern matching articles/explanations

[Ian Duncan]

Hello everyone, I've been working on improving my Haskell knowledge,  
and in doing so, I have read a little about as-patterns as well as  
some form of pattern that uses "~" that I don't really understand. I  
suspect there are even more lesser-known pattern matching expressions  
than just these, but I don't have the stamina to decode the Haskell  
98 Report. Are there any articles anyone is aware of, or anything in  
the Haskell wiki that covers the built-in pattern matching facilities  
pretty comprehensively? I've looked in the Haskell wiki myself, but  
information on different pattern matching abilities seems rather  
scattered and I'm not entirely sure what I should be looking for.

Thanks,
	Ian Duncan
