+Having too many elements in a tuple causes a compilation error. A workaround is to collect the extra elements in a nested tuple.

+error: [GHC-94803]
+    • A 65-tuple is too large for GHC
+        (max size is 64)
+        Workaround: use nested tuples or define a data type
+    • In the expression:
+        (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
