What is the rationale behind std.file.setAttributes ?

As much as I dislike PHP, I think they are onto something with 
having an optional stream context object that you can pass onto 
various file functions. It allows you to treat HTTP and the 
regular file system in the same manner (by having authentication 
etc in the context object).

Rather than setting attributes you would populate the context 
object (you could use a OS-specific factory function/class) with 
the settings you want and then pass it around. I guess you could 
then precreate one context for ReadOnly, another for 
ExecutableBinary, another for MIME text/html etc…
