Dear list member,
A solution
when you change a record (or the meaning of an integer) and want to
make sure that you are warned by the compiler at
every place where this data is used is to encapsulate your type in a box
replacing for instance
let x = 0 : int (number of eggs)
with
let box d = `A(d) and unbox (`A d) = d
let x = box 0 (*nomber of dozen of eggs*)
Once you have updated all your code, you can remove the "box" and "unbox".
It would be nice if all this could be automated ...
Cheers,
Christophe
