[Swift-devel] arrays of files

[Michael Wilde]

Replace your prior implementation of bar() with this, and you then have a reall array solution (workaround) until the @filenames() bug is fixed:

app ( file result ) barapp ( file files[], string s[])
{
   ls "-lt" s stdout=@result;
}

(file result) bar (file files[] )
{
  string s[];
  foreach f, i in files {
    s[i] = @filename(f);
  }
  result = barapp( files, s );
}
