How can I source the output from a Perl script?

Question

I'm looking for a way to accomplish this in a single statement:

./perlscript.pl ./inputFile "some option" > temp.sh; source temp.sh; rm -f temp.sh

temp.sh does

export ENV_VAR="some value"

and after the above commands echo $ENV_VAR reports some value.

I've tried

./perlscript.pl ./inputFile "some option" | source /dev/stdin

and the script runs, but the source doesn't seem to have worked; echo $ENV_VAR shows nothing. I feel like this is very close, but I've run out of ideas.

Any ideas?

source is basically "read a file and eval it"; how about eval "$(perl etc)" — user2404501

You can use process substitution like this:

source <(./perlscript.pl inputFile "some option")
