  • first, thank you. thank you. thank you.

    it seems you have transitioned perl6 development from 'smoldering' to 'blazing'... the invigorated discussions on the language list would be accomplishment enough, but clearly this is only a start...

    lucky for me, the 2 languages at the top of my list to learn for some time have been haskell and perl6 (in no particular order). your recent work has inspired me to work harder to realize this(i see the PUGS code base as a great way for me to kill 2 birds with one stone
    • Hmm, I sense a need of Perl6::Pugs::FAQ...

      The use of $ is not Template Haskell... The binary operator ($) simply means "apply function"; f $ g is equivalent to f g.

      The use of $ in Haskell code is for fixing precedence. For example, to calculate f(g(3)), one can write f $ g 3, or using the function composition, as (f . g) 3, but f g 3 will not work, as it means f(g, 3).

      "Yet Another Haskell Tutorial" is a fine online tutorial. The books I'm currently reading are:

      • Algorithms : A Functional Programming Approach (International Computer Science Series) By: Fethi A. Rabhi, Guy Lapalme
      • Types and Programming Languages By: Benjamin C. Pierce
      • Introduction to Higher-Order Categorical Logic (Cambridge Studies in Advanced Mathematics) By: J. Lambek, et al
      • Advanced Topics in Types and Programming By: Benjamin C. Pierce (Editor)
      • Basic Category Theory for Computer Scientists (Foundations of Computing) By: Benjamin C. Pierce
      • Purely Functional Data Structures By: Chris Okasaki
      • The Haskell School of Expression: Learning Functional Programming through Multimedia By: Paul Hudak
      • Haskell: The Craft of Functional Programming (2nd Edition) By: Simon Thompson

      I recommend the "Algorithms" book for Haskell newcomers; the other two introduction books by Thompson and Hudak are also quite pleasant to read.

      To trace the latest source tree, use one of the three source repositories linked from the Pugs page [haskell.org].

      As for development tools... I'm currently still using Vim, but Eclipse's Haskell support [sourceforge.net] is excellent.
