Currently, accessing information about an element in a document using data
structures is error prone.
For instance, iterating over a component_set and accessing current
component information look like this:
{{{
component_set<L> compset;
for_all_comps(comp, compset)
compset(comp).is_valid();
}}}
Here, ''comp'' is an ID, not the component itself. Moreover, it is
error
prone since several methods exists both in the container and in element
structure:
{{{
component_set<L> compset;
for_all_comps(comp, compset)
compset.is_valid();
}}}
This code would also work and may not lead to the expected result...
We want iterators to write the following code:
{{{
component_set<L> compset;
scribo_citer(component_set<L>) comp(compset);
for_all(comp)
comp.is_valid();
}}}
Iterators would also make the code more 'Milena style'.
