[Swift-devel] [Bug 343] New: Add support for optional input and output files

[Daniel S. Katz]

Basically, the functionality we want to replicate is an app that runs on all files in a directory, filling a new directory with output files. Then we run another app on each of those output files, more or less. We don't always know that the first app will generate an output file in each case, though it does >90% of the time.

Not doin the reduce on the array because an outfile was not mapped is the same as what swift currently does. The only difference is that instead of causing the swift system to fail it just tries to continue on the execution.
