wxruby users - Dec 2011 - 'open(f).each' doesn't close file

On Ruby 1.9.3 (win7(64))

''cause code says more the thousand words:
##################
 open("test.txt","r").each do end  # doesn''t close
file
 FileUtils.rm "test.txt"           # will fail: Permission denied
##################
(it doesn''t matter if the "do end" is filled or omitted)

Bug, ''Feature'' or my mistake?

What does this have to do with wxRuby?

...and yes, it?s your mistake. File.open without a block doesn?t close
the file: http://ruby-doc.org/core-1.9.3/File.html#method-c-open

What you?re doing in your code is calling File.open without a block
and then calling File#each with a block.
