It would be pretty damn cool if you could create a data type for

It is mostly because those libraries are far older than Text and
ByteString, so String was the only choice at the time. Modernizing them is
good.. but would also break a lot of code. And in many core libraries, the
functions are required to have String types in order to be Haskell 98

hsp support is in a separate package:

Still, "Haskell is an open source product" doesn't sound right to me.
Even "Haskell is open source" (without the "product") has a bad ring

If you search on google for 'haskell web framework' that link actually

Do you need to persistently store your Haskell data types in tables ?
Or just persistently store them ?
happstack-state provides the latter for you. Your data-types are just
plain-old Haskell data types and your queries and updates are just
