I'm just trying to make the entry point for SOAP as simple as possible.
I got thinking about this because other languages can do multi-arg
functions without a problem but ZSI only does one dictionary argument.

The SOAP spec say: "Each [in] or [in/out] parameter is viewed as an
accessor, with a name corresponding to the name of the parameter and
type corresponding to the type of the parameter. These appear in the
same order as in the method signature."

In other words order matters for RPC parameters!

$server = SOAP::Lite
        ->uri($ns)
        -> proxy($server_url);

print $server-> f2c(70, 90) 
        -> result;
