default(Int)
allows to use integers anywhere in this module without specifying their
ambiguous type each time, like this: (3::Int)
https://www.haskell.org/tutorial/numbers.html
section 10.4
some other default types may be specified too
somehow I was not aware of this

It is true that ambiguous types cause time-wasting frustration for many a
beginner.
The link that Imants gave helps clarify matters:
https://www.haskell.org/tutorial/numbers.html
Even better is the link to the Haskell report given at the end:
