This function iterates over each GPA in the input list, checks which condition it meets, and appends the corresponding letter grade to the `letter_grades` list. Finally, it returns the list of letter grades. The example test case provided should output `['A+', 'B', 'C-', 'C', 'A-']`.		 passed

To solve this problem, we need to convert a list of GPAs into corresponding letter grades based on a specific grading table. The grading table defines ranges of GPAs and their corresponding letter grades, starting from 4.0 (A+) down to 0.0 (E).

### Approach
1. **Special Case Handling**: If a GPA is exactly 4.0, it directly maps to 'A+'.
2. **Threshold Checking**: For GPAs other than 4.0, we check against a series of thresholds in descending order. Each threshold specifies a minimum GPA value (exclusive) and its corresponding letter grade.
3. **Fallback for 0.0**: If a GPA does not meet any of the thresholds and is exactly 0.0, it maps to 'E'.

### Solution Code
```python
def numerical_letter_grade(grades):
thresholds = [
(3.7, 'A'),
(3.3, 'A-'),
(3.0, 'B+'),
(2.7, 'B'),
(2.3, 'B-'),
(2.0, 'C+'),
(1.7, 'C'),
(1.3, 'C-'),
(1.0, 'D+'),
(0.7, 'D'),
(0.0, 'D-')
]
result = []
for gpa in grades:
if gpa == 4.0:
result.append('A+')
continue
for thresh, letter in thresholds:
if gpa > thresh:
result.append(letter)
break
else:
result.append('E')
return result
```

### Explanation
1. **Special Case Handling**: The code first checks if the GPA is exactly 4.0 and appends 'A+' immediately if true.
2. **Threshold Checking Loop**: For each GPA, the code iterates through a list of tuples where each tuple contains a threshold value and the corresponding letter grade. If the GPA exceeds the threshold, the corresponding letter grade is appended, and the loop breaks.
3. **Fallback for 0.0**: If none of the thresholds are met (i.e., the GPA is 0.0 or less), the code appends 'E' as the letter grade.

This approach efficiently checks each GPA against the thresholds in descending order, ensuring the correct letter grade is assigned based on the highest applicable threshold. The use of a for-else loop structure ensures that the fallback grade 'E' is correctly assigned when no thresholds are met.		 passed

### Explanation:
1. **Helper Function `get_letter_grade`**:
- This function takes a single GPA and returns the corresponding letter grade based on the conditions specified in the table.
- It uses a series of `if` and `elif` statements to check the GPA against the thresholds and return the appropriate letter grade.

2. **List Comprehension**:
- The main function uses a list comprehension to apply the `get_letter_grade` function to each GPA in the input list `grades`.
- This results in a new list where each GPA is replaced by its corresponding letter grade.

### Example Usage:
- The example `print(numerical_letter_grade([4.0, 3, 1.7, 2, 3.5]))` demonstrates how the function can be used to convert a list of GPAs into a list of letter grades.

This approach ensures that the code is both readable and efficient, making it easy to understand and maintain.		 passed
