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

I have the following code at the top of my Perl script: 
use Data::Dumper;
$Data::Dumper::SortKeys = 1;

[download]
This gives the following error: 
Name "Data::Dumper::SortKeys" used only once: possible typo at hello.p
+l line 24.

[download]
How do I correct this?

    Hello MrSnrub,

    The “keys” part of $Sortkeys is all lower case:

     0:59 >perl -MData::Dumper -wE "$Data::Dumper::SortKeys = 1;"
Name "Data::Dumper::SortKeys" used only once: possible typo at -e line
+ 1.

 1:00 >perl -MData::Dumper -wE "$Data::Dumper::Sortkeys = 1;"

 1:00 >

    Hope that helps,

    By using the correct symbol name:  $Data::Dumper::Sortkeys (was 'K' vice 'k'; Perl identifiers are case-sensitive). See Data::Dumper.

    Give a man a fish:  <%-(-(-(-<
