[DBIx-Class-Devel] [dbix-class] add ResultSet::rs to force scalar context (#68)

[andrewgregory]

Sure.  This is just meant to be a little more convenient, in the same way `$rs->search_rs` is more convenient than having to call `scalar $rs->search()`.  I find it more readable than using `scalar` or `search_rs` to force scalar context and, as you said, using `search_rs` involves a performance penalty.
