Allow #to_path object as argument to system()
I often work with Pathname objects, but when passing them to a system command I find it a bit tedious that they have to be explicitly converted to a String.
file = BASE + "config.json" system(@cmd, file) #=> TypeError (no implicit conversion of Pathname into String) system(@cmd, file.to_s) #=> works
I propose that the system/exec/spawn family of methods should try to convert their arguments using
to_str fails. I believe it makes perfect sense, since commandline arguments are so often pathnames.
This includes in/out redirection.
system("ls", out: Pathname.new("file")) should be valid.
