[Swift-devel] output format of simple_mapper

[Michael Wilde]

When I apply this mapping to a 2D array of files:
   file result[][] <simple_mapper;
                      prefix=@strcat("output/",p,"/"),suffix=".pdt">;

then I get files like:

   output/T1di2/0004.0001.pdt

but when I apply this mapping to a 2D array of structs of files:

   OOPSOut result[][] <simple_mapper; prefix=@strcat("output/",p,"/")>;

then I get files like:

   output/T3cpo/0000_0000.pdt

Not a problem, just curious what motivated the difference (of sub1.sub2 
vs sub1_sub2)?
