In know this syntax primarily from Ruby's blocks.

This would allow writing

  var foo = {|a, b, c| ...};

which could be written even shorter as

  var foo(a, b, c) {...};

The later is more consistent with the following which would also be
necessary at times.

  lambda(a, b, c) {...}

I'd prefer the last two options.

The following please!

  (lambda (a b c) ...)

;-)
