Dynamically choosing the main function

GHC allows choosing a main function at link time using the "-main-is"
option. I was wondering if there is a possibility to choose the main
function at runtime. Or even better, if something equivalent to "ghc -e"
is somehow possible in a linked binary executable. If not, are there any
plans to achieve something like that in future? Are there any theoretical,
practical obstacles to that?
