I discussed about this form with Tom.

I thing so following should be readable:

name: [ optional => ] value
 SELECT foo( bar: 'ick', baz: 'ack' ); SELECT foo( bar: => 'ick', baz: => 'ack' );

or
 SELECT foo( bar: = 'ick', baz: = 'ack' );

reason for optional using of "=>" is too thin char ":", so =>
optically boost the colon.

this is 100% compatible because syntax name: is new token
