SOAP::Lite and hashrefs

cLive ;-) has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to send a hashref as an argument to a SOAP server. I'm dumping the args to a log on the server and they look fine, but I get a warning when running the client:

Cannot encode 'hashref' element as 'hash'. Will be encoded as 'map' in

And, here's the weird bit. I was just running an adapted sample from the docs that begins with:

#!perl -w
[download]

When I change this to:

#!/usr/bin/perl
use strict;
use warnings;
[download]

the warning disappears.

Is there a difference between the -w switch and the "use warnings" pragma?

confused...

ps - I'm running these as "perl script.pl" rather than "./script.pl"

Is there a difference between the -w switch and the "use warnings" pragma? yes, and this has been asked before, e.g. here	[reply]

OK, so I now get the difference, but that brings up another question... Trawling through SOAP::Lite, I see they use a local $^W to supress warnings, and use $^W to decide whether to warn or not. Since $^W stays at 0 when "use warnings" pragma is used, is it fair to say that the weirdness is bad programming practice from the SOAP::Lite developer(s), or should I be using -w and "use warnings" and just let it go? cLive ;-)	[reply]

is it fair to say that the weirdness is bad programming practice from the SOAP::Lite developer(s), `use warnings;` is relatively new to Perl. Any modules that were created before it might not be completely rewritten to include it, and any modules written when it was new may not have used it in order to be backwards compatible with earlier versions of perl. So, it may be more of a kludge to make it work then bad programming Want to support the EFF and FSF by buying cool stuff? Click here.	[reply] [d/l]
