> 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.
