Desugaring of pattern matching function

[rvdalen]

Hi everyone,

If I write a function using "pattern matching function" syntax:

==================

boolToString2 :: Boolean -> String

boolToString2 true = "value is true"

boolToString2 false = "value is false"

==================

Is this just syntactic sugar which really converts that syntax into:

==================

boolToString :: Boolean -> String

boolToString v =

  case v of

    true -> "value is true"

    false -> "value is false"

==================

Yep, it absolutely is.

You can see it if you look at the generated JS for both...
