| Another way of doing a shallow copy of a numerically indexed table is simply by using unpack like this:
t1 = {
"every",
"good",
"boy",
"deserves",
"fruit",
}
t2 = { unpack (t1) }
The unpack call unpacks the original table (t1) into individual items, which are then used in the table constructor for t2. Thus, t2 contains the same items as t1, but t1 and t2 are different tables. |
