Is there a way to reliably call operators such as eq, ne, etc. on an object which you know has those operators overloaded? However, I don't want to make assumptions about the class of the object.

Here's an example: 

sub create_selector {
  my ($spec) = @_;
  my $selector;
  if ($spec =~ m/^=(.*)/) {
    $selector = sub { $_[0]->version eq $1 }
  } elsif ($spec =~ m/!=(.*)/) {
    $selector = sub { $_[0]->version ne $1 }
  } elsif ($spec =~ m/>(.*)/) {
    $selector = sub { $_[0]->version gt $1 }
  }
  $selector;
}

my $selector = create_selector("=6.2");
...
my @selected_dists = grep { $selector->{$_} } @list_of_dists;

The idea is that I could write create_selector like this: 
sub create_selector {
  my ($spec) = @_;
  my $selector;
  if ($spec =~ m/^(=|!=|<|>)(.*)/) {
    my $op = $1;
    my $method = ...translate $op to a method name...
    $selector = sub { $_[0]->version->$method($2) }
  }
}

That is, I want to be able to perform the translation of $op to a method name in a way which will work for whatever object I'll be applying it to.
