#4684 — File.open options hash "mode" as int

Hello.
in 1.9.x, I see that these work:
File.open('yo', 'w')
File.open('yo',  File::WRONLY|File::TRUNC|File::CREAT)
File.open('yo', :mode => 'w')

So shouldn't this also work?

>> File.open('yo', :mode => File::WRONLY|File::TRUNC|File::CREAT)
  TypeError: can't convert Fixnum into String

Well, the docs say this:

===
IO.open(fd, mode_string="r" [, opt] ) → io
IO.open(fd, mode_string="r" [, opt] ) {|io| block } → obj

Document-method: IO::open

With no associated block, open is a synonym for IO.new.
===

===
IO.new(fd [, mode] [, opt]) → io

Returns a new IO object (a stream) for the given IO object or integer 
file descriptor and mode string. See also IO.sysopen and IO.for_fd.
Parameters
fd:  numeric file descriptor
mode:  file mode. a string or an integer
opt:  hash for specifying mode by name.
===

The last line there seems to be why you are getting the error.

File::WRONLY|File::TRUNC|File::CREAT is numeric...

..and what does the last line of the docs I posted say?

I guess this is why.  I just don't see quite *why* it requires mode by 
name in opts, but accepts it by int when given as a parameter.  But that 
makes sense.

A few more notes.

> IO.open(fd, mode_string="r" [, opt] ) → io

Yeah, interestingly, this doesn't look at all like
File.open('filename')
so...the docs just lack the most common usage of File.open apparently? 
Odd.
