Turtle and Observer Command

se, sentence `anything1 anything2`

Returns a list. If `anything1` and `anything2` are lists, it concatenates the two lists (combines their items into one list). If `anything1` is a list and `anything2` is not, it puts `anything2` at the end of the first list. If `anything1` is not a list and `anything2` is a list, it puts `anything1` at the front of the second list. If both `anything1` and `anything2` are not lists, it creates a new list containing both `anything1 and anything2`.

Examples:

se 1 2 returns [1 2]

se [1] 2 returns [1 2]

se 1 [2] returns [1 2]

se [1] [2] returns [1 2]
