How to deal with errors in <()?

[Peng Yu]

Hi,

http://mywiki.wooledge.org/ProcessSubstitution

The above webpage says the following.

commandA <(commandB; [commandB's exit code is available here from $?])
[commandB's exit code cannot be obtained from here.  $? holds
commandA's exit code]

But I am wondering if there is a walkaround to deal with errors in
<(). The ideal behavior should be that if there is a error in <(),
then we should not consider commandA is executed correctly even if its
return status is 0.

Does anybody have a good solution for this situation? Thanks.
