"e.g. instead of print "<$element->{name}>";, use print '<', $element->{name}, '>';
Personally, I'd prefer:
printf '<%s>', $element->{name};
Update: just for the heck of it, this ain't too bad either:
print "<$_>" for $element->{name};
Using postfix for to temporarily alias $_ is an idiom I don't see used very much, but is quite cute, and in this case has no speed penalty (quite the opposite in fact)...
use strict; use Benchmark ':all'; open $::dummy, ">", \$::data; cmpthese(100_000, { print_for => q[ $::data = ''; print {$::dummy} "<$_>" for "a" ], printf => q[ $::data = ''; printf {$::dummy} "<%s>", "a" ], }); __END__ Rate printf print_for printf 7663/s -- -79% print_for 36765/s 380% --
(PS: kcott's follow-up was posted before this update, so please don't read it as necessarily endorsing the for postfix technique.)
