Keef has asked for the wisdom of the Perl Monks concerning the following question:

I have a two variables, how do I justapose them so they create a 3rd variable. Like so:
$var1 = "cream";
$var2 = "coffee";
$var3 = $var2 " & " $var1;
print $var3 # returns "coffee & cream"

    To quote the Beasty Boys, "I like my sugar with coffee & cream". Moving on... 
    $var3 = "$var1 & $var2";
$var3 = $var1 . " & " . $var2;
$var3 = join ' & ',$var1,$var2;
undef $var3;
$var3 .= $_ for $var1 =~ /./sg,' ','&',' ',split//,$var2;

    The string concatenation operator is .

    Applying this operator is left as an exercise.

    The usual answer is to use interpolation. 
    print "$var2 & $var1"; # Prints "coffee & cream"

    That is why all of those funny little symbols are used, to make it easy to drop variables directly in strings...

    I'm not sure I understand what you mean by juxtapose but this works for me- 
    $var1 = "cream";
$var2 = "coffee";
$var3 = $var2 . " & " . $var1;
print $var3 # prints "coffee & cream"

    which uses the '.' operator to concatenate the strings, is that what you wanted?
