The boring stuff, like building nice parameterized SQL queries and getting back the data from SQL. Launching a system process in parallel and keeping track of its status (and potentially aborting it if e.g. it takes too long)
If we do all of the boring stuff in a clean, concise way, that makes everything easy, with the option of adding macros on top to boot, the boring stuff might well become fun, or at the very least, painless.
Some times ago I started a GTK+ binding, now "paused". It's more boring than I thought initially. If you wish look at it for a starting point (file gtk.arc in Anarki). I now think a binding towards tcl/tk would look nicer and easier to use, though.
These would require a standard FFI system. Or else we would end up writing Anarki specific code. Such a fork would be a real Arc killer (in the bad sense of the term).
sacado built an FFI on Anarki.... well forks are generally bad but with PG asleep until october or so .... (maybe he's getting ready for oktoberfest or something ^^)
