# This clever hack is courtesy Matt Webb:
# http://interconnected.org/home/more/GoogleSearch.pl.txt
# Redefine how the default deserializer handles booleans.
# Workaround because the 1999 schema implementation incorrectly doesn't
# accept "true" and "false" for boolean values.
# See http://groups.yahoo.com/group/soaplite/message/895

# 1) The SERVICE_CACHE->{foo} syntax causes Perl
# Perl 5.00502 to break since the "inlined
# subroutined-ness" of scalar constants
# https://rt.cpan.org/Ticket/Display.html?id=1753
# 2) Rather than creating a whole bunch of separate
# subroutines to abstract away all the ($] > 5.00502)
# stuff, I might as well just tack the '&' on
# now and be done with it.
