I suspect it's a convinces that falls out of the wash due to the way the
rest of Lua works.  I find using it with "local" and such to be much
more succinct and readable than setting each variable individually.

It's also useful for swapping things without a temporary variable:

t = { "foo", "bar" }
t[1], t[2] = t[2], t[1]
