And note we are pushing precisely on the use of DSLs in or on Haskell for *portability* of the domain-scientists code in a number of areas right now:
* data parallel algorithms (targetting cpu , gpu) Accelerate: http://hackage.haskell.org/package/accelerate-0.6.0.0 Obsidian http://www.cse.chalmers.se/~joels/writing/dccpaper_obsidian.pdf
Another good example: Cell DSL, for Maple users: A Domain-Specific Language for the Generation of Optimized SIMD-Parallel Assembly Code http://www.cas.mcmaster.ca/~kahl/Publications/TR/Anand-Kahl-2007a_DSL/ "a domain-specific language embedded into Haskell that allows mathematicians to formulate novel high-performance SIMD-parallel algorithms for the evaluation of special functions.
