i having issues understanding sml's syntax nested let s , if s. example, why syntactically ill-formed? fun stuff = let val p = 2 in if = 1 let val r = p in = r end else 0 end if a 1 make a equal to r , if a not 1, not create r in first place , return 0. kinda stupid, o well... so, why syntactically incorrect? it not syntactically incorrect. type error. the problem both branches of if need have same type, whereas then -branch has type bool ( a = b comparison, not assignment, if assignment, it'd have type unit , wrong type) , else -branch has type int . can make code compile returning boolean in else branch this: fun stuff = let val p = 2 in if = 1 let val r = p in = r end else false end ps: note can assign ref s in sml, if wanted assign a in code, you'd need make int ref rather plain int .
