Very interesting! Thanks. The idea comes from 10 years of working with them as an external vendor. I see all sorts (but especially Python and C++) on prop desk

Very interesting! Thanks. The idea comes from 10 years of working with them as an external vendor. I see all sorts (but especially Python and C++) on prop desks, but mostly C# in other areas (integration, data management etc.) That being said, nearly all of my experience is in front office trading and asset management, primarily in listed instruments, with little on OTCs, and nothing on payment processing, 'core banking' or the kind of stuff that spans the entire organisation. It sounds like Haskell has found a niche at Standard Chartered doing perhaps just that. What are those two banks you mentioned doing with their Haskell code?
