Embedded Domain Specific Language means that you embed a Domain specific language in a language like Haskell. E.g. using the functionalMetaPost library you can write Haskell expressions, which are then translated to MetaPost, MetaPost is run on the generated code and the result of MetaPost can be post-processed in Haskell.

Discussion of common problems

Sharing and recursion are common problems when implementing DSLs. Often some kind of observable sharing is requested.
