[davishmcclurg (David Harsha)]

ARGF provides helpers for processing file/stdin command line arguments in various ways (bytes, chars, codepoints, etc), but it doesn't currently have a simple way to iterate through the arguments as File/IO objects. This can be useful when you want to perform an operation on the contents of an entire file (eg, JSON parsing) instead of combining them into a single string or going line-by-line. My proposal is to add an ARGF.each_file method that yields each file (or returns an enumerator if no block is provided).
