I wonder if it is possible to embed regular HTML code inside gitit (on

A safe recursive definition would be

However, if you leave out the constructor,
let x = x + 1
you get a loop (or a deadlock).
Are there any other reasons?

From time to time, I've wanted to have a more pleasant way of writing
point-free compositions of curried functions. One might want to
transform both the first and second arguments, for instance, or only
the third argument, of a curried function. I've never known a
(non-cryptic) way to do this.

Numeric literals are special. Their type is (Num t) = t, so it can
belong to any type that is instance of Num. Whereas Test belongs to
Test type only so you cannot call bar on any instance of Foo.
So your pattern constrains type signature of bar more then it is
constrained by class

Yes; I had a similar question, and it turns out Num is special, or
rather, pattern matching on integer literals is special. See the

The summary is that pattern matching on a literal integer is different

I think that Anatoly was suggestion a bridge between markdown and haddock
syntax.
Of course gitit would read haddock-documented sources and generate different
results than haddock itself (showing highlighted source code is the most
significant).
