Hi,
So in Lua, as far as I can say, there is no way to express directly
something like `a = {b=1, c=a.b}`.
Instead one might use functions, and call the table with the instance
method call operator (colon), like
`a = {b=1, c=function(s) return s.b end}; a.b == a:c() -- true`.
A first minor problem is that it introduces asymmetry in form. A
solution which would allow to call equally
`a.b` and `a.c` would be more interesting for this use case.
Moreover, `a.c = 2` should lead to a state where `a.b == a.c and a.b == 2`
More context: the goal is to store lexicological informations in data
modules.
Entries might share one or more descriptive material. The important
point which lead to this consideration
is that the data module should be modifiable from outside the module,
without requiring huge integrity
constraint at each description change.
But maybe I'm not taking the simplest approach here, so feel free to
suggest totally different solution.
Kind regards
