With a little discipline, field name typos can be caught usefully:

http://lua-users.org/wiki/StrictStructs

e.g.

struct.Point {X = 0, Y = 0}

p1 = Point() -- defaults to {X=0,Y=0}
p2 = Point {X=2,Y=10}

print(p1.x)  ---> oops! No such field!

The other advantage is that it encourages developers to name all those
anonymous data structures which we create so happily and then struggle
to document.
