the examples for AWS certification validations https://www.pulumi.com/registry/packages/aws/api-docs/acm/certificatevalidation/ assume that only a single domain validation output is returned; however in practice AWS can return more than 1 (as described by https://pkg.go.dev/github.com/pulumi/pulumi-aws/sdk/v5/go/aws/acm#CertificateOutput.DomainValidationOptions) . so the example code here should be ranging over all of the outputs rather than assume there is only 1. I can't figure out how to get the length of the array without crashing. Example code is:

domainValidationOption := exampleCertificate.DomainValidationOptions.ApplyT(func(options []acm.CertificateDomainValidationOption) interface{} {
            return options[0]
        })

^ DomainValidationOptions type is CertificateDomainValidationOptionArrayOutput which has an Index() method but not an associated Len() method. If I use Index() that exceeds the length of the array I get a pulumi crash:

    error: an unhandled error occurred: program exited with non-zero exit code: 2

how are callers supposed to get the length of DomainValidationOptions? followup would be can pulumi update the referenced example code to include this?
