No matter where the indentation is, where clause should not be present at this position.

The where clause is fine in bindings that feellike a = b where c. According to the language report, where clause is a part of RHS, and RHS is as shown below:

and GDRHS is just the guarded right-hand side as

GDRHS → guards = EXP[GDRHS]

Hence, where clause can be of use when using “=,”orwhile making a binding.
