The point about sed is that sed can substitute whatever you like into

ok, please can you give me an example sed-command which replaces ${.*}
with the according environment-variables? I couldn't find this yet and
nobody could point me to it yet. The only way to do this I seeing atm is
to iterate through $(printenv) and replace all listed
environment-variables in the stream using sed. But this way seams very
"bloat" to me.
And when i write such a tool for myself, why does it matter if i do this
with python, perl, ruby, php, c or something else?
