Hi guys, Having completed a simple parser project using Haskell, I'm getting more and more "hooked" on functional-programming in general and Haskell in particular. And learning the language has been a real treat as well, using the tutorial with occasional peeks at the report. However, when I'm considering undertaking more complex projects, I realize that there is one important erea of the Haskell language that is still pretty much a "black-hole" for me: the run-time environment. I honestly can't say that I completely understand how the actual control and data flows work when a Haskel program is executed, and I seem to be constantly surprised by the garbage-collection, which sometimes seems as if it doesn't work at all, and at other times seems to do magic. I've tried reading some of the articles related to the design of GHC's run-time. But they don't seem to be much help. They either assume that the reader has prior knowledge of functional-programming run-time environments, or get into very low-level details. And at the end of the day, this is very confusing, and I find terms like thunks, entries, partial-function-applications, etc. floating in my head hoplessly seeking anchor. So, where can one find a good introductory book / article on the subject? Thanks, -Jony __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
