< "$@" doesn't expand properly?

hello everyone,

I wrote a simple "inplace" script to be able to
work with commands that have no -i options.

The simplest way to do it (I thought) was

#!/bin/sh
set -eux
< "$@" | sponge "$1"

so inplace counter awk '{$0+=2}1' would be expanded
as

< 'counter' 'awk' '{$0+=2}1' | sponge 'counter'


but there is an error message

./inplace: 3: cannot open counter awk {$0+=2}1: No such file

so it seems that the expansion leads to

< 'counter awk {$0+=2}1' | sponge 'counter'

is this an expected behavior?

regards
