Automatically use redirection to capture return status of unnamed pipe?

[Peng Yu]

Hi,

In the following command, the return status does not capture the
errors in the unnamed pipes.

set -o pipefail
paste <(seq 3; false) <(seq 11 13; false) || echo "$?"
1       11
2       12
3       13

The following command is equivalent to the above command, except that
the return status captures the error. But the code is less readable.

{ seq 3; false; } | {
        { seq 11 13; false; } | paste /dev/fd/3 /dev/fd/4 4<&0
} 3<&0 || echo "$?"
1       11
2       12
3       13
1

Is there an automatic internal translation of the code in bash so that
the first command can be still used and the errors are still captured?
Thanks.
