SE-0279: Multiple Trailing Closures [Amended]

[Ben_Cohen]

Moderation note

I've been thinking the same thing. This is really unclear:

text.drop { $0.whitespace }

It might be worth moving the argument label into the base name:

text.dropWhile { $0.whitespace }
text.dropWhere { $0.whitespace }

While I agree, this is really a separate discussion from the review, so I've started a thread to discuss this particular issue. Please discuss the potential changes to the standard library there.

It's a fine line, because discussion of the rules for multiple trailing closures is perhaps helped by considering the current challenges of labels with trailing closures. But specifically addressing what exists in the standard library should go in the other thread.
