RegEx feels overkill for this. Certainly takes longer to read, understand and
test.
Here's a more convincing example, let's build an imaginary data format parser:
```python
data = '''\
scores:
- Matthew: 100
- David: 90
groceries:
- spam: 3
- eggs: 12
'''
parsed = {}
for line in data.splitlines():
match line:
case f"{heading}:"
parsed[heading] = {}
case f"- {name}: {count}":
parsed[heading][name] = int(count)
print(parsed)
# Gives {'scores': {'Matthew': 100, 'David': 90}, 'groceries': {'spam': 3,
'eggs': 12}}
```
