Issue Description:

The following code

import Foundation

struct Object {

    private func _doResize<Location>(
        includeHeader: (Int, Location) -> Bool,
        includeCell: (IndexPath, Location) -> Bool,
        includeFooter: (Int, Location) -> Bool
    )
    {
        withoutActuallyEscaping(includeHeader) { includeHeader in
            __doResize1(
                includeHeader: includeHeader,
                includeCell: includeCell,
                includeFooter: includeFooter
            )
        }
    }
    
    private func __doResize1<Location>(
        includeHeader: @escaping (Int, Location) -> Bool,
        includeCell: (IndexPath, Location) -> Bool,
        includeFooter: (Int, Location) -> Bool
    )
    {
        withoutActuallyEscaping(includeCell) { includeCell in
            __doResize2(
                includeHeader: includeHeader,
                includeCell: includeCell,
                includeFooter: includeFooter
            )
        }
    }
    
    private func __doResize2<Location>(
        includeHeader: @escaping (Int, Location) -> Bool,
        includeCell: @escaping (IndexPath, Location) -> Bool,
        includeFooter: (Int, Location) -> Bool
    )
    {
        withoutActuallyEscaping(includeFooter) { includeFooter in
        }
    }

}

results in the following output:
