freestyle OP fix output:
``` hello world [0, 2, 4, 6, 8] *skylark.List [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] ``` |

Skylark is a dialect of Python intended for use as a configuration language. Like Python, it is an untyped dynamic language with high-level data types, first-class functions with lexical scope, and garbage collection. Unlike CPython, independent Skylark threads execute in parallel, so Skylark workloads scale well on parallel machines.
这个可以做内嵌脚本系统用了 |
