 Corner case with tuples: 'b' should give the same error as 'a'.

 {{{

 <interactive>:2:9:
     A 63-tuple is too large for GHC
       (max size is 62)
       Workaround: use nested tuples or define a data type

 (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)

 ghczmprim_GHCziTuple_Z63T_static_info
 This may be due to you not asking GHCi to load extra object files,
 archives or DLLs needed by your current session.  Restart GHCi,
