Hi,
A weird question, what does the 1 element tuple look like?
() -- 0 element tuple
(,) a b -- 2 element tuple
(,,) a b c -- 3 element tuple
() a - meaningless
(a) - a in brackets
GHC has the 1 element unboxed tuple, (# a #), and all the other sizes
unboxed as well, but how would you visually represent the 1 element
boxed tuple?
Tuples represent dimensionality therefore a 1-element tuple is just a
1-dimensional value ie the value itself hence a == (a) == ((a)) == (((a)))
