ghcjs --interactive not supported

[fisx]

opening this in the hope that it's a simple mistake of mine and easy to fix. thanks for the great work!

$ stack exec -- ghcjs --interactive
ghcjs-0.2.1.9007019-8.0.1.bin: --interactive is not yet supported.
Usage: For basic information, try the `--help' option.

stack.yaml as in https://docs.haskellstack.org/en/stable/ghcjs/, tried with lts-7.1 and lts-7.19.

thoughts after a quick search:

the discussion in commercialhaskell/stack#337 looks like this feature has been working since 2015. perhaps ghcjs just needs to be built in a different way, like with some extra flag?

the nix setup for reflex has the same issue: reflex-frp/reflex-platform#96

Ah, it's not supposed to work with ghc8: ghcjs/ghcjs#171

too bad. sorry for opening this bogus issue, please close. but perhaps it'll help others looking into this.

Yes. use lts-6.30.
For the 8.0 branch: ghcjs/ghcjs#549
