Work out a way to use articles for tense assignment

> In addition ri/le/we articles do not only refer to physical closeness, but can also refer to temporal distance: ri indicates things in the past, or not yet done; le refers to things recently done, with relevance to the present; we refers to things just done, going on right now.

Maybe something like,

* impf + ri = imperfectivo ``
* perf + ri = pasado simple ``
* impf + le = presente ``
* perf + le = pasado `haber + `
* impf + we = presente ``
* perf + we = pasado `haber + `

But where should be determiner/article come from? Subject/Object/Obliques?

Of course these would need to be overridden with tense concordance (e.g. between matrix and subordinate clause).
