== Description

Return `true` if the specified `lhs` and `rhs` nullable objects have the same value, and `false` otherwise. Two nullable objects have the same value if both are null, or if both are non‐null and the values of their underlying objects compare equal. Note that this function will fail to compile if `LHS_TYPE` and `RHS_TYPE` are not compatible.

== Return Value
