in thread Escaping special characters for POD output

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;

    My casual testing confirms slowdown but not that significantly. Can you provide some texts for benchmarking?

      I didn't do any benchmarking.
