Dear Lispers,

apart from a new and improved run-program featuring asynchronous support thanks to Elias Pipping, the ASDF master branch (currently at 3.1.7.37) also features some long announced cleanups of internals:

* instead of using operation class names (symbols) as keys to various internal tables, whereby ASDF can't distinguish between multiple operations of same type, operation objects are used instead. * this required making sure that operation objects are always created using MAKE-OPERATION, which can hash-cons them when created with compatible options. * this also required eliminating the current original-initargs mechanism, which was abused by SWANK and ECL in non-sensical ways, but never used to build distinguishable operations (nothing could). * there is currently no more mechanism to build distinct operations of a same class, and so each operation class is currently a singleton. But in the future some mechanism might be added e.g. to support cross-compilation. Or not.

Swank was fixed. An alternative implementation of ECL's MAKE-BUILD has been offered, but I'd like to stop making this function part of ASDF itself: ECL can provide its own add-on it they care for this function, it just was never a good fit for ASDF, that provides better APIs since 3.1.2 (May 2014). That said, Robert is the person to convince whether to keep shipping MAKE-BUILD or not.
