Announcing: My miscellaneous Ikarus libraries

I have some various things I've made for Ikarus at:

https://code.launchpad.net/~derick-eddington/+junk/derick-ikarus-misc

Most useful to others are probably:

* Preliminary port of Pattern Matching for Scheme by Andrew K. Wright and Bruce Duba.
  (No struct/record support, box support needs to be removed, and maybe other
   irrelevant/broken stuff needs to be removed/fixed)

* Port of Oleg's delimited control.
  (Planned to be multi-thread-safe in the future)

* Enhanced define syntaxes: define-values, define* which does procedure currying and
  unspecified values, and define-syntax* which does procedure style.

* Continuable interrupts: allows resuming of an interrupted (right now only via Ctrl-C) computation.
  (Surely to be surpassed in the future by real debugging support)
  I.e:
