[Swift-user] Expanding arrays in app function command lines

[Michael Wilde]

Thanks, Ben.  The example looks good - that seems the natural way to 
express it.

Might want to specify/test the following:

- array of other scalar types, coerced into string in the cmd line
- struct? (expand the fields in source-code order)?
- array of struct etc

Or for now just fail the cases that are not easy to support?

The struct case would be handy for the oops code that is using the 
parameter-string array case: the app returns 5 files; would be nice to 
specify them as a struct type and pass a single argument for results 
called "oops_results". Same for its 3 input files.

- Mike
