For the first two it would not make a difference, since they are
essentially closed constructs, following the offside rule which
inserts a } at the place where they end, so this cannot give rise to
an ambiguous interpretetation. One might even argue that their current
precedence level in the Haskell definition is "suboptimal".
The "if" is a different thing, due to the absence of offside rules for
