Hello Locutus,

I assume your sample data are (over-)simplified for the purposes of illustration? The problem is, I find it hard to extrapolate from the example given to a more realistic scenario. Let S = { treasure, tree, train }. Do you want to construct the partition S = { treasure, tree } ∪ { train } by distinguishing words beginning with tre from others? Or should S be a single partition of words beginning tr? I think a more complex example would go a long way towards clarifying what you are trying to accomplish.

A preliminary search of the CPAN threw up the String::REPartition module. While this isn’t what you’re looking for, it might give you some useful ideas.

Hope that helps,
