in reply to escapeHTML & scalar/array context

You could always just change the way you feed escapeHTML, without any sort of wonky join: 
map {print $q->escapeHTML($_)} Data::Dumper::Dumper($foo,$bar);

Is that more of what you are looking for? It's a "clean" output of the answer, sans string munching.

    map {print $q->escapeHTML($_)} Data::Dumper::Dumper($foo,$bar);

    map in void context is evil. Use map to generate a list, not to just loop over something. Use the for modifier for that. 

    print $q->escapeHTML($_) for Data::Dumper::Dumper($foo, $bar);

    Or use map the way it is supposed to be used: 
    print map $q->escapeHTML($_), Data::Dumper::Dumper($foo, $bar);
print map { $q->escapeHTML($_) } Data::Dumper::Dumper($foo, $bar);
