Ok, done.

RuleData is referenced later after the Request. Mode has no meaning by itself without the Request.

It improves the reference locality.

To improve the Reference locality. RuleData is referenced later, after the Request. The Mode is also referenced later at Request. By itself it has no meaning (mode of what?).

What exactly?

For me it is a lot! It allows instantly and easily see the difference in the return types of different constructors.

Seems so, I could not find where it is used.

OK.

Good. Consider putting a space between m and {.

Yes, the documentation is better this way.

Please provide the reason for relocating RuleData and Mode.

How relocation of RuleData improves the code?

Indentation.

1468ca0b-2a64-4fb4-8e52-ea5806644b4c commented 6 years ago

Please use 2 or 4 spaces for indentation. Odd number of spaces is... odd.

Most of Halon code uses 2 space indentation — the default value used by Emacs' haskell-mode. I find 2 spaces to be too narrow and use 4 [*]: Haskell code is dense, narrow indentations hinder the readability. (Linux kernel uses 8-chars indentation for a good reason.)

[*] I use 2-chars indentation for where lines, records, lists... E.g.

foo = bar
  where  -- indented with 2 spaces
    bar = undefined  -- 4 spaces of indentation

data Rec = Rec
  { f1 :: Int  -- 2 spaces of indentation, but the field itself starts at column 4
  , f2 :: Char
  } deriving Show

data T
  = T1
  | T2 Float
  | T3 (Text, Int)
  deriving (Eq, Show)

What's the point?

Please revert.

[optional] Squeezing excessive spaces into one would be an improvement though.

Please don't. This group of changes does not improve readability.
