Dear Don Stewart,
  +
  +
Thank You very much for Your kind letter.

== Categorising ==
  +
  +
=== New category or having already? ===
  +
  +
I looked at all category names to decide where ''Combinatory logic'' and ''Dependent types'' should fit.
  +
I think You are right, and ''Theory'' would be a good new category, or ''Foundations''.
  +
It could contain articles like e.g.
  +
* Lambda calculus
  +
* Combinatory logic
  +
* Type theory
  +
** Dependent types
  +
* Category theory
  +
** Categorical programming
  +
* Formal languages
  +
** Attribute grammars
  +
* Linguistics
  +
** Applicative universal grammars
  +
etc. Maybe it would become a natural category for projects like Quantum Computing -- I saw there are a lot of QC materials concerning Haskell -- and quines (see bottom of this letter) too.
  +
  +
=== ''Articles'' or ''Foundations''? ===
  +
  +
The category name ''Articles'' seems to me too structural (instead of functional):
  +
* ''Foundations'' describes a ''role'', a ''funtion''
  +
* ''Articles'' refers to a structure, a format.
  +
To decide between them, let us see the crosscutting cases:
  +
* a page on foundations, but not in an article format, e.g. a categorical programming language interpreter
  +
* an article on practical things, e.g. on conventions
  +
maybe we cannot avoid all croscutting, but I think ''Foundations'' provides a better modularity.

I thought of creating a Combinatory logic page.

Dependent type

Hey, is there a way these pages (on combinatory logic, dependent types, and so on) can be categorised? and then be found easily from the front page?

They're not quite 'Idioms', but perhaps we need a new category for 'Theory' or 'Articles'

Categorising and linking pages Combinatory logic and Dependent types

Dear Don Stewart,

Thank You very much for Your kind letter.

Categorising

New category or having already?

I looked at all category names to decide where Combinatory logic and Dependent types should fit. I think You are right, and Theory would be a good new category, or Foundations. It could contain articles like e.g.

  • Lambda calculus
  • Combinatory logic
  • Type theory
    • Dependent types
  • Category theory
    • Categorical programming
  • Formal languages
    • Attribute grammars
  • Linguistics
    • Applicative universal grammars

etc. Maybe it would become a natural category for projects like Quantum Computing -- I saw there are a lot of QC materials concerning Haskell -- and quines (see bottom of this letter) too.

Articles or Foundations?

The category name Articles seems to me too structural (instead of functional):

  • Foundations describes a role, a funtion
  • Articles refers to a structure, a format.

To decide between them, let us see the crosscutting cases:

  • a page on foundations, but not in an article format, e.g. a categorical programming language interpreter
  • an article on practical things, e.g. on conventions

maybe we cannot avoid all croscutting, but I think Foundations provides a better modularity.

Linking

How to link these articles from the front page: First I thought, I put a link to them from

  • Learning Haskell
    • Books and tutorials
      • Foundations

do You recommend other linking paths from the front page? I show some possible linking path maps below, showing the changes with typesetting boldface and with prefixing exclamation mark:
