Issue #10815 has been updated by Daniel Berger.


Ok, but that seems a strange way to declare the function prototype. Compare that with Dir.entries, which does give you an error if you pass the wrong number of arguments.

Bug #10815: Dir.foreach in block form does not allow encoding

----------------------------------------
It doesn't appear that Dir.foreach{} allows an encoding:

    enc = Encoding::UTF_16LE

    # Without a block, works ok
    p Dir.foreach(Dir.pwd)      # => Enumerator
    p Dir.foreach(Dir.pwd, enc) # => Enumerator

    # With a block, fails if more than 1 argument is passed
    p Dir.foreach(Dir.pwd){ }      # => nil
    p Dir.foreach(Dir.pwd, enc){ } # => ArgumentError
