Problem
In
EquateComparable, passing an untypednilvalue results inreflect.TypeOf(typ)returningnil. Attempting to callt.Comparable()directly onnilleads to an unhandled runtime nil pointer dereference panic.Solution
t == nilinEquateComparablebefore callingt.Comparable(), raising the formatted panic message consistently.util_test.gofor invalid inputs (niland non-comparable function).
