I've included the output of "git diff HEAD". As well, the source code in non-patch format can be found in this github repo: http://github.com/ekiru/rakudo/tree/argfiles
I know there has already been a submission, but I had already gotten a significant part of this implemented when I saw it, and it didn't have support for actually initializing the $*ARGFILES contextual. I also went ahead and implemented some IO methods that weren't mentioned in Moritz's original post(.ins for example). I also modified lines() to use $*ARGFILES as the default IO object according to the spec. I've given it a little testing, but I can't guarantee there are no bugs, and I know that it will behave weirdly if not everything in @*ARGS is a filename or "-". Similarly to Perl 5's magic <>, it mutates and refers to @*ARGS(which means that if there are non-filename arguments but you remove them before you try to read from them in $*ARGFILES, no problems will ensue). I was uncertain about when exactly to initialize $*ARGFILES, since it isn't mentioned in the spec. I decided to insert the initialization immediately after @*ARGS is initialized. It should be safely movable to any point when the setting and @*ARGS are available, though. -- Tyler Curtis
