- Fixed several bugs in lux.lux
- Fixed an error in lux.base/analyse-2
- Modified the analyser so the symbols that identify all of the special forms must mandatorily have "" as their prefix.
- Fixed a bug in the binary operations at lux.analyser.host wherein the types where being omitted.
- Fixed a bug when closing-over variables inside lambda bodies wherein the names of bindings where being stores as (incomparable) arrays, instead of as (comparable) strings.
