[DiegoAlpizar]

• Replaces 'M' to '_' as a placeholder in partial
• Important alias fix: reject -> discard
• Add one ) in tap example to properly close ...:tap(function(v) print('Max is', M.max(v) end)
• Corrects final result in tap example: now ...:value() --=> Max is 81 instead of ...:value() --=> Max is 89
• Corrects "whilelisted" -> "whitelisted"
• Fix typos in curry example
