Hi dear monks, I came over a strage behaviour with print/say built-ins using setlocale. I tried to localize floating point representation using setlocale. I observed different behavior of print/say statements according to how I use them. If I use a point operator to concatenate some numbers and strings to a single statement
say "bla bla" . 1/2 . " bla bla
prints "bla bla 0.5 bla bla". If I pass a list the localized german represantation with comma is used
say 'bla bla ', 1/2, ' bla bla'
prints "bla bla 0,5 bla bla".

Please explain this behaviour if it is intended. The code which demonstrates the problem using say and print statements is below. I use Strawberry Perl 5.10 on Windows XP SP3. 
use strict;
use warnings;
use diagnostics;
use v5.10;
use locale;
use POSIX qw(locale_h);
setlocale (LC_ALL, "german") or die "failed to load locale!";


my $number = 1/2;
say 'output of say';
say $number;
say 1/2;
say 1/2 . " concatenate";
say 1/2 , " list";
say "1/2 concatenate";
say "1/2 list";
say $number . " concatenate";
say $number , " list";

say 'output of print';
print "$number\n";
print 1/2 . "\n";
print 1/2 . " concatenate\n";
print 1/2 , " list\n";
print "1/2 concatenate\n";
print "1/2 list\n";
print $number . " concatenate\n";
print $number , " list\n";

this prints on my machine:
output of say
0,5
0,5
0.5 concatenate
0,5 list
1/2 concatenate
1/2 list
0,5 concatenate
0,5 list
output of print
0,5
0.5
0.5 concatenate
0,5 list
1/2 concatenate
1/2 list
