== Why is this an issue?

Using trailing closure syntax for the last parameter in a call is often the most elegant way to handle it. But if the call requires multiple function-type arguments, the use of a trailing closure can be messy and confusing. In such cases, it's better to pass closure expressions as normal arguments.


=== Noncompliant code example

[source,swift]
----
var x = complexOperation(
  arg: 2,
  op1: {$0 + 10}
) {$0 * $0}
----


=== Compliant solution

[source,swift]
----
var x = complexOperation(
  arg: 2,
  op1: {$0 + 10},
  op2: {$0 * $0}
)
----

\[~ann.campbell.2] you understand the rule in a wrong way. The thing is that you can use trailing syntax only for the last parameter. 

I changed description, could you verify it?
