Some notes for beginners on how to pronounce those strange Haskell operators etc.

This is just a rough start to this page. Obviously needs more work.

This can be a table with formal and informal ways of saying various operators and code snippets such as

Symbol Pronunciation
 ::
has type (in definitions); at type (in expressions or patterns)
 ->
maps to, to
 =
is
 ==
equals
 /=
not-equals
 =>
is a witness for, implies
 .
dot (could be used anywhere, but especially in, for example, Data.Char.ord), ring, compose (for example, negate . (+1)), (silent) (for example, forall a. (Num a) => a)
 <-
drawn from, from
 -<
 ++
append
 >>=
bind
 >>
then
 \
lambda
 !
bang; strict (in patterns or data definitions); index (in expressions)
 ~
irrefutable, lazy (in patterns)
 :
cons
 []
nil
 ()
unit
 (,)
2-tuple, pair
 (a,b,c)
[3-]tuple [of] a, b, and c
 ({)}
just as inconvenient to convey grouping verbally, whether it's layout or punctuation
Example Pronunciation
f :: Int -> Int
f has type Int to Int

should we add informal, possibly bad suggestions like "then", "is", "gets"?
