Hi,

Cperl-mode does not highlight properly function names that contain
Perl keywords.

Here is a test case.

------------

#!/usr/bin/perl

sub test_read_file ()
  {

  }

sub func ()
  {

  }

------------

You will notice that 'read' in test_read_file is highlighted as
a keyword whereas 'func' is hightlighted as a function name.

I could reproduce the problem with current CVS trunk as well.

Cheers,
