Hi,

there is no bug here.  Type
  wml -p12 filename
to see which input file is sent to ePerl.  It looks like
  <:
    $bid = 2C;
  :>
which is invalid Perl code, and causes this error.  You have to add
quotes to fix this, e.g.
     $bid = '%body';
or
     $bid = q{%body};
or
     $bid = <<'HERE'
  %body
  HERE
  ;
You have to choose a delimiter which cannot appear in %body.
