Subject: sed script fails to run in dash

Hi,

I am puzzled and don't know why this command does not work with dash (I
am currently using the debian stable (v7.2) version of dash (v0.5.7-3)):

echo 1>/tmp/x; reponse=$( sed -e $(wc -l </tmp/x)$'{w/dev/stdout\n;d}'
-i /tmp/x ); echo "reponse='$reponse'"

but also just this line:

    sed -e 1$'{w/dev/stdout\n;d}' -i /tmp/x

in a dash script will yield the error message:

    sed: -e expression #1, char 2: unknown command: `$'

But why ? :(

I would be really grateful for any explanation.
Thanks a lot in advance for any hint!
