One development that has been cooking for months but has gotten a lot of attention lately is Joshua “eggyknap” Tolley's PL/LOLCODE. It's a procedural language flavor of LOLCODE used to access PostgreSQL databases. One of the things that really sold it for me was Selena Deckelmann's exemplary slides that she gave for a local PerlMongers meeting.
CREATE OR REPLACE FUNCTION
gimmeh_dinnr() RETURNS TEXT AS $$
HAI
GIMMEH OUTTA DATABUKKIT "SELECT food FROM bowl ORDER BY time DESC LIMIT 1"
FOUND YR IT
KTHXBYE
$$ LANGUAGE PLLOLCODE;
