Subject: Remove dead code from CDBICompat::ImaDBI
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=35ca725a;p=dbsrgits%2FDBIx-Class-Historic.git

Remove dead code from CDBICompat::ImaDBI

This is a forgotten piece from back in 902133a3, overtaken by a local copy of
Class::DBI::SQL::Transformer. Nothing called/exercised it since then
