I considered that.  I suppose the wildArgv code could go in 
std.path, and the file operations into std.file. and the pull 
requests against those files.

I haven't followed the discussions closely enough to know what 
are the rules/politics about adding another std library import 
into those.  It would require adding import of std.parallelism 
into std.file.
