#   - {name: CPP, within: CrossPlatform} # CPP can only be used in a given module
#
# - flags:
#   - {name: -w, within: []} # -w is allowed nowhere
#
- modules:
  #  if you import Data.Set qualified, it must be as 'Set'
  # - {name: Control.Arrow, within: []} # Certain modules are banned entirely
  - {name: [Data.HashMap.Strict], as: HashMap}

# Will suggest replacing "wibbleMany [myvar]" with "wibbleOne myvar"
# - error: {lhs: "wibbleMany [x]", rhs: wibbleOne x}


# Turn on hints that are off by default
#
# Ban "module X(module X) where", to require a real export list
# - warn: {name: Use explicit module export list}
#
# Replace a $ b $ c with a . b $ c
# - group: {name: dollar, enabled: true}

# Generalise map to fmap, ++ to <>
- group: {name: generalise, enabled: true}

# Ignore some builtin hints
- ignore: {name: Use String}
# - ignore: {name: Use let}
# - ignore: {name: Use const, within: SpecialModule} # Only within certain modules

# Define some custom infix operators
