brought up six in a messy, undisciplined way, she had started all over again with another baby late in life (M. Dickens).
With the gerund introduced by a preposition of time the perfect is more often than not neutralised. E.g.: He was at Cambridge and after taking his degree decided to be a planter (S. Maugham).
Cf. the perfect gerund in a strong position: The memory of having met the famous writer in his young days made him feel proud even now.
Less liable to neutralisation is the infinitive. The category of retrospective coordination is for the most part consistently represented in its independent constructions, used as concise semi-predicative equivalents of syntactic units of full predication. Cf.:
It was utterly unbelievable for the man to have no competence whatsoever (simultaneity expressed by the imperfect). — It was utterly unbelievable for the man to have had no competence whatsoever (priority expressed by the perfect).
The perfect infinitive of notional verbs used with modal predicators, similar to the continuous, performs the two types of functions. First, it expresses priority and transmission in retrospective coordination, in keeping with its categorial destination. Second, dependent on the concrete function of each modal verb and its equivalent, it helps convey gradations of probabilities in suppositions. E.g.:
He may have warned Christine, or again, he may not have warned her. Who can tell? Things must have been easier fifty years ago. You needn't worry, Miss Nickolson. The children are sure to have been following our instructions, it can't have been otherwise.
In addition, as its third type of function, also dependent on the individual character of different modal verbs, the perfect can render the idea of non-compliance with certain rule, advice, recommendation, etc. The modal verbs in these cases serve as signals of remonstrance (mostly the verbs ought to and should). Cf.: Mary ought to have thought of the possible consequences. Now the situation can't be mended, I'm afraid.
The modal will used with a perfect in a specific collocation renders a polite, but officially worded statement of the presupposed hearer's knowledge of an indicated fact. Cf.:
175
"You will no doubt have heard, Admiral Morgan, that Lord Vaughan is going to replace Sir Thomas Lynch as Governor of Jamaica," Charles said, and cast a glance of secret amusement at the strong countenance of his most famous sailor (J. Tey). It will not have escaped your attention, Inspector, that the visit of the nuns was the same day that poisoned wedding cake found its way into that cottage (A. Christie).
Evident relation between the perfect and the continuous in their specific modal functions (i.e. in the use under modal government) can be pointed out as a testimony to the category of retrospective coordination being related to the category of development on the broad semantic basis of aspectuality.
