You mean:

Sample:
This worked under previous bash versions (I use 5.0.3(1)-release):
testForkInput () {
local line
while read line ;do
echo "$line"
done < <(
sed 's/^/> /'
)
}
But with 5.1.0(1)-beta, I have to replace this with:
testForkInput () {
local dup line
exec {dup}<&0
while read line ;do
echo "$line"
done < <(
sed 's/^/> /' <&$dup
)
exec {dup}>&-
}
testForkInput < <(seq 1 5)
