In my book 'Gramática de uso del Español C1-C2', unit 71 is dedicated to infinitivo
, and there are two sentences using infinitivo compuesto
:
¿No queréis ir? Haberlo pensado antes.
¿Que estás cansado? Haber descansado cuando pudiste antes.
To me, it seems it is used to express something which should have happened/been done in the past, but hasn't. What is this form and where can I read more about it? I tried to search for it but as I don't know the grammatical term, I couldn't find anything.
