 Using [https://github.com/ppelleti/hs-mercury-api this package], I tried
 doing "stack repl" with GHC 8.0.2:

 {{{
 whiteandnerdy:hs-mercury-api ppelleti$ stack repl
 The following GHC options are incompatible with GHCi and have not been
 passed to it: -threaded

 * * * * * * * *
 The main module to load is ambiguous. Candidates are:
 1. Package `mercury-api' component exe:tmr-firmware with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-
 firmware.hs
 2. Package `mercury-api' component exe:tmr-gpio with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-gpio.hs
 3. Package `mercury-api' component exe:tmr-lock with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-lock.hs
 4. Package `mercury-api' component exe:tmr-params with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-params.hs
 5. Package `mercury-api' component exe:tmr-read with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-read.hs
 6. Package `mercury-api' component exe:tmr-write with main-is file:
 /Users/ppelleti/programming/haskell/hs-mercury-api/examples/tmr-write.hs
 You can specify which one to pick by:
  * Specifying targets to stack ghci e.g. stack ghci mercury-api:exe:tmr-
 firmware
  * Specifying what the main is e.g. stack ghci --main-is mercury-api:exe
 :tmr-firmware
  * Choosing from the candidate above [1..6]
 * * * * * * * *

 Specify main module to use (press enter to load none): 4

 This bug appears to have been around a while, because it also happens with
 GHC 7.8.3:
