Grammar as a phenomenon – a subsystem of language as a linguistic discipline

The "aspect view": according to this interpretation the perfect is approached as an aspective form of the verb. (Vorontsova)

The great merit of G. N. Vorontsova's explanation of the aspective nature of the perfect lies in the fact that the resultative meaning ascribed by some scholars to the perfect as its determining grammatical function is understood in her conception within a more general destination of this form, namely as a particular manifestation of its transmissive functional semantics.
Indeed, if we compare the two following verbal situations, we shall easily notice that the first of them expresses result, while the second presents a connection of a past event with a later one in a broad sense, the general inclusion of the posterior situation in the sphere of influence of the anterior situation:
The wind has dropped, and the sun burns more fiercely than ever.
"Have you really never been to a ball before, Leila? But, my child, how too weird —" cried the Sheridan girls.
The resultative implication of the perfect in the first of the above examples can be graphically shown by the diagnostic transformation, which is not applicable to the second example: → The sun burns more fiercely than ever as a result of the wind having dropped.

• 
  The "tense-aspect blend view"; in accord with this interpretation the perfect is recognised as a form of double temporal-aspective character, similar to the continuous. (Ivanova)
  

According to I. P. Ivanova, the two verbal forms expressing temporal and aspective functions in a blend are contrasted against the indefinite form as their common counterpart of neutralised aspective properties.

NB!
2 meanings of one category cannot be expressed in one categorical form!

Smirnitsky showed the categorical nature of perfect and proved that it is the category different from both tense and aspect.

Tense, aspect – the same was asking – had been asking

The meaning does not denote the time of action but shows relative priority . Unlike non-perfect forms it correlates the action with the indicated moment or event in its result.

Smirnitsky: TENSE vs ASPECT vs ORDER
The meaning of Perfect forms is constituted by 2 semantic components: temporal (priority) and aspective (result)
The meaning of Perfect can be influenced by the lexical meaning of the V, tense form, context.
Perfect forms and the lexical character of the verb (durative and terminative)
Perfect forms and the context (inclusive and exclusive perfect)

(Verbals have the category of order but no category of tense => different category)
