[Haskell-cafe] Need some help figuring out how to use the repl with reflex using only stack

[Sridhar Ratnakumar]

This doesn't directly answer your question, however in the case that all
you want is to get started with a simple Reflex-DOM app, I'd suggest
starting with obelisk:
- https://github.com/obsidiansystems/obelisk
- https://youtu.be/riJuXDIUMA0?t=30m15s

Then you can just run `ob repl` to get into the repl.

cheers,
