Moving key & values from one table to another

[Chris <coderight@...>]

Are there any tricks to insert all the keys and values of one table into another?

For example:

t = {}
t.a = "a"
t.b = "b"
t.c = "c"

u = { unpack(t), d="d", e="e" }

I know you can't use unpack except on numbered index values.   Is
my only choice a table.foreach with an insert of each value from `t'
into `u'?
