How to deal with multiple input args?

Is it possible to provide multiple input args to a function?
So something similar to
```
@input_schema('foo', StandardPythonParameterType('foo))
@input_schema('bar', StandardPythonParameterType('bar'))
@output_schema( StandardPythonParameterType(True))
def run(foo, bar):
    ...
```

The examples don't mention this, and I haven't been able to get it to work by myself.
