[Swift-devel] arrays of files

[Michael Wilde]

Yup, thanks, Mark - its a bug.

if you change the body of bar to read:

   ls "-lt" @filename(files[0]) @filename(files[1]) stdout=@result;

instead of:

  ls "-lt" @filenames(files) stdout=@result;

then it works.

I'll file a bugzilla ticket on this. David, can you add to the test suite? Mihael, can you fix it?

Thanks,

- Mike
