Haste was designed to allow both the client and server to be written as parts of the same, type-safe application. This is in stark contrast to most other options, where the client and server are considered two separate entities, resulting in extra manual validation code and more chances for type errors.
Question Ranking
Pros
Pro Client and Server as the same application
Haste was designed to allow both the client and server to be written as parts of the same, type-safe application. This is in stark contrast to most other options, where the client and server are considered two separate entities, resulting in extra manual validation code and more chances for type errors.
Pro Almost full power of Haskell
Haste supports the Haskell 2010 standard except for Template Haskell as well as most GHC extensions.
Pro Automatic, type safe program slicing
Haste lets you write client and server as a single program, automatically generating code for the server as well as the client, giving you full type safety even across the Internet.
Pro Generates small, reasonably performant code
Pro Easier transition from other paradigms
Since F# is not a purely functional language, it lends itself to being more easily picked up by programmers that have experience with other paradigms.
Pro Concise syntax
F#'s syntax tends to be terse while remaining very readable and easy to understand without being a chore to write.
Pro Runs on the CLR
Since F# runs on the Common Language Runtime or CLR, it has access to the entire .NET Framework, as well as libraries written in other .NET languages such as C#, VB.NET, and C++/CLI.
Cons
Con Lacks some minor Haskell functionality
Lacks support for Template Haskell.
Con Not really cross platform
Though the community sites are touting F# can be cross platform through use of Mono, the reality is that it is more of a hack to replay on larger mono applications in production.
