yaml_config = """\
# Server configuration
host: localhost  # default host
port: 8080
# Enable debug mode for development
debug: true
"""
result = literalize_yaml(
    yaml_string=yaml_config,
    language=Go(),
    wrap=True,
)
# result:
# map[string]any{
#     // Server configuration

#     "port": 8080,
#     // Enable debug mode for development
