IO::Tokenized::File adds the methods provided by IO::Tokenized to IO::File objects. See the IO::Tokenized manpage for details about how the tokens are specified and returned.
IO::Tokenized::File inherits both from IO::tokenized and IO::File, so that methods from both classes are available to IO::Tokenized::File objects.
IO::Tokenized::File redefines the following methods:
new([$filename[,@tokens]])new method is redefined so as to call both
IO::File::new (passing to $filename if it is defined) and
IO::Tokenized::new (passing to it the @tokens parameter).
open($filename)open method from IO::File is redefined so that only opening
for input is allowed: requestes for other kind of opening are silently
converted to oepning for input (this is a bug).
