COBOL (or perhaps these days Cobol, lower-case) just received a new edition of its standard last year. By far its most major overhaul was in 2002, with the introduction of OO and recursion.

Not to say that you should be quick to build your startup on COBOL, but the present language is pretty tolerable. Most of the COBOL that actually runs, I think, is 74-era code, however. That is certainly painful.

It could always be worse, however. It could be MUMPS.
