The prefix symbol

[Stephen Colebourne]

Prefix character summary after 2 days:
PLEASE DON'T TRY TO VOTE ON YOUR FAVOURITE

Use #
  #(x) { return x + 1; }
  #{x -> x + 1}

Use ^
  ^(x) { return x + 1; }
  ^{x -> x + 1}

Use \ (from another thread)
  \(x) { return x + 1; }
  \{x -> x + 1}

Use $  (concern over parsability, as it is part of an identifier)
  $(x) { return x + 1; }
  ${x -> x + 1}

Use _  (concern over parsability, as it is part of an identifier)
  _(x) { return x + 1; }
  _{x -> x + 1}

Use @
  @(x) { return x + 1; }
  @{x -> x + 1}

Use λ   (concern over being unicode)
  λ(x) { return x + 1; }
  λ{x -> x + 1}

Use :
  :(x) { return x + 1; }
  :{x -> x + 1}

Use ::
  ::(x) { return x + 1; }
  ::{x -> x + 1}

(I'm not listing keywords that have been suggested elsewhere)

Issues around typing the various characters on different keyboards
have been raised.

Some options would permit use as an alternate method reference syntax character.

*** Final call ***, does anyone have a character they prefer more than
one of the those above that they want to be considered?
Remember, this isn't a vote, or a discussion thread, but a "gathering
the options" thread.
PLEASE DON'T TRY TO VOTE ON YOUR FAVOURITE
