// Refs v0.5.754: `obj[strKey](args)` computed-key method call now
// dispatches through the class vtable chain (parent inheritance
// included). Pre-fix this fell through to the generic call path that
// read obj[index] as a value (returning undefined for class methods)
// and then tried to call undefined. Drizzle's
// `this.session[isOneTimeQuery ? "prepareOneTimeQuery" : "prepareQuery"](...)`
// chain depends on this.
