Parentheses as pipes is what you do when you’ve backed yourself into a corner.

Ruby has decided (for some reason?) to use two ways to declare.

Function(param, param)

and

{ |param, param| }

why? What is a good reason for this?

It would be an anti pattern in design, not sure why Ruby gets a special hall pass.

   collect: [ :keyAndValue | (keyAndValue splitAt: '=') last ].

is why.

EDIT: (it's been a few months since I used it, so I) made a mistake in the syntax (declared local variable instead of a formal block argument), it's fixed now.

You might as well have leaned on the keyboard, it wouldn’t look much different. This is not readable code.
