-- Page 12 on the 0.12.0-screen version of the book | |
-- You start step 2 with the following lambda: | |
(\x.\y.\z.xy(yz))(\m.\n.\m)(\p.p) | |
-- You then reduce it, in step 3 to the following: | |
(\y.\z(\m.\n.\m)z(yz))(\p.p) | |
-- I believe that this reduce is missing a period after the first z, and instead should read like so: | |
(\y.\z.(\m.\n.\m)z(yz))(\p.p) | |
-- If this is indeed a mistake, and not my own misunderstanding, it carries on throughout the example. |
