Comment (by redneb):

 Currently, when you run `runhaskell script.hs arg1 arg2`, `ghc` is called
 with the following arguments:
 {{{
 -ignore-dot-ghci -x hs -e ':set prog "script.hs"' -e ':main ["arg1",
 "arg2"]'
 }}}
 Note the the `["arg1", "arg2"]` part is generated by calling `show` on the
 list of original arguments. This is very inefficient. One solution is to
 introduce a new flag for `ghc` that would directly interpret the specified
 file. The new flag must have a short name so that the length of `"ghc"`
 plus the length of the flag name plus 1 (for the null character) is less
 than the length of `"runhaskell"`.
