in reply to Text::Levenshtein - trouble

Text::Levenshtein is returning in list context, but scalar context is what should be happening. You could force scalar context by using scalar. For example:
#!/usr/bin/perl -l use autodie; use strictures 1; use Devel::SimpleTrace; use strict qw/refs/; use Text::LevenshteinXS qw/distance/; my $x = scalar distance("history", "history"); my $y = scalar distance("gistory", "history"); my $z = scalar distance("history", "hustory"); print $x, "\n", $y, "\n", $z; use strict qw/refs/; use Text::Levenshtein::Damerau qw/edistance/; $x = scalar edistance("history", "history"); $y = scalar edistance("gistory", "history"); $z = scalar edistance("history", "hustory"); print $x, "\n", $y, "\n", $z; use strict qw/refs/; use Text::Levenshtein; $x = scalar distance("history", "history"); $y = scalar distance("gistory", "history"); $z = scalar distance("history", "hustory"); print $x, "\n", $y, "\n", $z;
