• SR-6913 Default arguments are not evaluated correctly in larger expression

Issue Description:

Values of #file/#line/#column/#function are different depending on context.

Consider two functions:

public func log(file: String = #file, line: Int = #line, column: Int = #column, function: String = #function) {
    print(file + ":\(function)" + ":\(column)" + ":\(line)")
}

public func log2(descriptor: String = #file + ":\(#function)" + ":\(#column)" + ":\(#line)") {
    print(descriptor)
}

Should these two functions print identical results? As of Xcode 10.2.1 values are different. Default values for `log` are evaluated in context of caller, when values for `log2` are evaluated in context of callee. Please see playground reproducing this in the attachment.
