The -main-is option to runghc does not appear to work.

[cjs]

The -main-is option to runghc does not appear to work, at least not when specifying a package name. Create Hello.hs:

    module Hello where
    main = putStrLn "Hello."

and then try to run it:

    runghc -main-is Hello Hello.hs

You will see:

    <interactive>:1:113:
        Failed to load interface for `Main':
          Use -v to see a list of the files searched for.

Thanks for the report. Happily, this has already been fixed (see #1312), although note that you need to escape Hello:

runghc -main-is --ghc-arg=Hello Hello.hs
