and and or have been exposed in the Prelude for 22+ years. They were in by
Haskell 1.2 from 1992 at latest, and where possibly around earlier.
Any pain they cause is *long* since over.
Adding nand and nor for trivial compositions causes fresh pain for anyone
already using those names ... to save 3 characters.

Again, if 'and' and 'or' are exposed without it being a problem, 'nand' and 'nor' could be too without causing a dramatic namespace pollution. --- Prelude.hs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
