Strange. It works for me on Linux with Perl 5.8.3. Some quick tests show that the arguments to a class's import function are identical for both the command-line version and the use statement. Maybe it's time to fire up the debugger or add some print statements to your encoding.pm?

Update: Here are the small test programs I used. They can probably tell you what's different between cygwin and cmd.exe.

T56.pm:

package T56;
 
use base 'Exporter';
sub import
{
  my $class = shift;
  print "$class import @{[scalar(@_)]} items: @_\n";
  my $fh = $_[0];
  print $fh "Ouput to first param\n";
}
1;
[download]

t56:

use T56 STDOUT,  bar => 'baz';
[download]

Compare the output of these to see what's different:

perl t56
perl -MT56=STDOUT,bar,baz -e 1
[download]

End of Update

Here's my Perl info:
