Re^6: Use module only if it is in use

Shouldn't that have a relevant overhead when used as:

while ($line = <F>) {
  chomp($line);
  $line = rarely_called($line) if $asciify;
  ...
}

BTW, I did something like that (using eval), but checking a flag to require the module only in the first call.

Benchmark and find out. Or use the self-loading alternative. Or split the initialisation from the actual use. `require Text::Unidecode if $asciify; while ($line = <F>) { chomp($line); $line = Text::Unidecode::unidecode($line) if $asciify; ... }` [download]	[reply] [d/l]
