Subject: [Xml-compile] Syntax errors when loading
	XML::Compile::Dumper-generated module
Message-ID: <CAMnMuOGT-0YvzmHfDyuKbn92hM5jfp42q-pbkHHK7YSea2=tFw@mail.gmail.com>

I'm trying to use XML::Compile::Dumper to freeze and then reload compiled
SOAP clients for the Avalara AvaTax web service, but I'm receiving syntax
errors when I try to load the resulting Perl module.

I've posted the generator script and resulting module to Github Gist here:
https://gist.github.com/mjgardner/af277f5204558e32554d

And these are the errors I get (auth info scrubbed):

Not all Data::Dump::Streamer versions have the same bugs.

It apparently decodes

  lib/XML/Compile/SOAP.pm
      my @pairs = ( %{delete $data->{Header} || {}}
                  , %{delete $data->{Body}   || {}});


into
  my(@pairs) = ( %{{} unless delete $$data{'Header'};}
               , %{{} unless delete $$data{'Body'};});

which is explainable but incorrect Perl.
You may be able to get this resolved.

XML::Compile::Dumper may not help your performance at all:
Data::Dump::Streamer should have some de-duplication implemented.

Sadly the previous several versions of DDS (2.09 through 2.37) do not pass
tests and install cleanly on my Mac OS X 10.10 Yosemite system. The latest
version 2.38 does, though.

Meaning: file a bug for DDS? Or hand-correct it after freezing?

Can you offer other suggestions on improving startup performance?

File a bug.
Of course, you could fix it by hand first, to see whether this is
the only problem.

Make it a daemon or process in bulk.
