> When a bigint is implicitly cast to a double (when a bigint is involved in an
> equality expression with a string or double) precision may be lost, resulting
> in unexpected behavior. Until we fix the underlying issue we should throw an
> error in strict mode, and a warning in nonstrict mode alerting the user about
> this.
