Taking a look at tags, we have perfect-aspect and past-tense (hell, we have past too, probably created by mistake) and we also have present-perfect and past-perfect.
On one hand, classifying tenses like [tense aspect] tense is one of the commoner grammar-myths; and on the other hand many learners may only be familiar with this kind of classification.
Should we have tags focusing on one aspect or tense or do we prefer the likes of the non-existent present-perfect "tense" as our tags?
