I'm a bit confused how this can have worked... in Haskell `let' is used in the context of a `let ..<1>.. in ..<2>..' where the code ellided in <1> binds some names to values which are then used in the expression <2> (as in `let x=sqrt 2 in exp x') and so the contents of main isn't (unless I'm missing something) syntactically Haskell.
Beats me, but it was the only (or at least the first) way I could find to create a function inside a do block...
You don't need to create a function, you could use partial parametrization instead: | main = | do content <- getContents | loop (report content) alphabet [snip] HTH, Jan de Wit
