The prefix symbol

[Jack Moxley]

how about the @ it might be used for annotations as well but it could quite happily sit along side.  

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

Prefix character summary after 15 hours:

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

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

Use a \ (from another thread)
\(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.

Once again, does anyone have a character they prefer more than one of
the three above that they want to be considered? Remember, this isn't
a vote, or a discussion thread, but a "gathering the options" thread.
