Hi Carl,

Apart from "indicator: submit", that was all that was in the form.

Nope, none of that.

Whatever happens inside :FormConfig('test') does it.

CentOS 5 perl-5.8.8-10.el5_2.3

Well, I narrowed it down to Catalyst::Plugin::StackTrace.  Upgrading
to StackTrace 0.09 makes the warnings go away.

Despite the obtuseness of the existing code, it appears that it's ~10x
faster than using reftype():

perl -d -e 0 -MBenchmark -MScalar::Util

timethis(1000000, 'eval { my $b = %$a }')

1 wallclock secs ( 0.51 usr + -0.01 sys =  0.50 CPU) @ 2000000.00/s (n=1000000)

timethis(1000000, 'Scalar::Util::reftype($a)')

10 wallclock secs (10.99 usr +  0.05 sys = 11.04 CPU) @ 90579.71/s (n=1000000)
