Haskell XMLRPC server executing dynamically generated functions

I have a Haskell RPCXML (HaXR) server process, run with GHC, 开发者_StackOverflowthat needs to execute any function that it's passed. These functions will all be defined at runtime so the compiled server won't know about them.

Is there a way to load a function definition at runtime? A method that avoids disk IO is preferable.

Thanks.

Although to load a function definition I think you will either have to put it into a module, or re-interpret it every time you use it.
