Should have known I was missing things.

The module doesn't escape «>» which is significant when generating the content of tags.

my $s = '$a <=> $b';
my $pod = "C<" . pod_quote($s) . ">";  # Fails

The modules doesn't escape «/» and «"» which are significant when generating the content of L<> tags.

my $s = 'Module for This/That';
my $pod = "L<" . pod_quote($s) . "|Some::Module>";  # Fails

Creating a hash with the replacements should be faster than what you're using now.

Note that «<» only requires escaping when preceded by an ASCII capital letter.

Thanks a lot! Didn't realize one might use pod_quote() to insert text inside a POD link. I've incorporated all your suggestions and uploaded version 0.002.

ow, the leading look-behind will slow things down a lot.

my %transforms = (
    ( map { "$_<" => "$_E<lt>" } 'A'..'Z' ),
    ">"  => "E<gt>",
    " "  => "E<32>",
    "\t" => "E<9>",
    "="  => "E<61>",
    "/"  => "E<sol>",
    "|"  => "E<verbar>",
);

 
s{ ( [A-Z]< | [>/|] | ^[ \t=] ) }{$transforms{$1}}g;
