Is the JavaScript embedding in HSPClientside essentially the same as
the embedding explained in Broberg's thesis?
Yes, in principal the core modules are based on the thesis.
Combinators and higher level functions are built on top of these.

This seems to contain just what I was looking for. Although I'm not
using HSP, it looks like the HSPClientside library can be used (in
conjunction with Text.XHtml) to generate webpages with embedded
scripts.
It sure should be possible to use HSPClientsi

So far, so good... However, problems arises trying to define the function :

For some reason it seems like the type checker
Hi. I have a type inference related problem which causes me some confusion. The following is a simplified example capturing the key aspects. First of all, consider a data type (here called) Elem and a type class IsElem.
data Elem = Eclass IsElem a where toElem :: a -> Eleminstance IsElem Elem whe
Hi. I came a cross the following phenomena which, at least to me, occurs kind
of awkward. The code below :
data MyData a where
DC1 :: (Show a ) => a -> MyData a
instance Show (MyData a) where
show (DC1 a ) = show a
yields the ghci error :
'Could not deduce (Show a) from the context (Sho

Yes, in principle that illustrates the idea.
However I don't see the major difference from constraining the
'a' to the IsFoo class, as in
instance IsFoo a => Class2 (Bar a) a

Hi.
I have a question regarding type classes and FunDeps.
Consider the following code :
> class Class2 a b | a -> b
> class IsFoo a

> instance IsFoo a => Class2 (Bar a) a
The last two instantiations will yield a 'Functional dependencies conf
