---
- &CENTER { x: 1, y: 2 }
- &LEFT { x: 0, y: 2 }
- &BIG { r: 10 }
- &SMALL { r: 1 }
# All the following maps are equal:
- # Explicit keys
x: 1
y: 2
r: 10
label: center/big
- # Merge one map
<< : *CENTER
r: 10
label: center/big
- # Merge multiple maps
<< : [ *CENTER, *BIG ]
label: center/big
- # Override
<< : [ *BIG, *LEFT, *SMALL ]
x: 1
