File dependency checking failed when inline shell command in for loop

[GoogleCodeExporter]

Given following pipeline:

$ cat foo.pipe
function foo
{
        SP_for_parallel _X=$(ls ~)
        {
                #[input="${_X}" output="${_X}.txt"]
                echo ${_X} > ${_X}.txt
        }
}

$ seqpipe -m foo.pipe foo -t 10
WARNING: File dependency defined in SP_for_parallel block in 
/home/yanll/foo/foo.pipe(3)
   NOTE: Such definition could make procedure dependency undeterminable.
ERROR: ERROR: Input file '$(ls ~)' does not exist!

Here, the input file string has not been expanded correctly.
