Quote:
The present perfective is common in temporal as well as conditional clauses for a future event that precedes the future event referred to in the matrix clause:
[6] When I’ve read the chapter I’ll put the kettle on.
[7] When they've scored their next goal, we'll go home.
[8] As soon as I've retired, I'll buy a cottager in the country.
[9] After they have left, we can smoke.
[10] If I've written the paper before Monday, I'll call you.
A common alternative for [7-10] is the simple present, which is excluded from [6] because the
when-clause is durative. A less common alternative alternative permitted for [6], is
will or (in BrE optionally with
I or
we)
shall plus perfective, eg:
When I’ll have read the chapter I’ll put the kettle on.

Nie rozumiem dlaczego
durative clause pozwala na
will + perfective, a
punctual(?) nie. Oba wskazują na "a future event that precedes the future event referred to in the matrix clause".
Poza tym, will + perfective ma być 'less common'. Czy użylibyście tutaj tej konstrukcji albo spotykacie się z nią w użyciu dzisiaj w tego typu zdaniach?
