Hmm, I thought specifying a type is always a restriction compared to
saying nothing at all and thus allowing everything.

If I don't specify a type, what's the inferred type of f? If I restrict
f to the exact same type it should do no harm. At least, that is what I
expected.


So, I do understand your explanations but I don't understand the reasons
for them. I will go and consult the literature on the ML typing system.

Thank you all for your replies.

Greetings
