## [0.2.1] - 2023-03-30

### Changed
- this is fundamentally a working Lisp. The reader reads S-Expressions fully and M-Expressions at least partially. It is not (yet) a feature complete Lisp 1.5.

### Added
- working `EVAL`, `APPLY`, `READ` and 24 other basic functions, of which at least four are not actually parts of the Lisp 1.5 specification. However, sufficient are present to allow the
vast majority of Lisp 1.5 functions to be defined.

### Known to be missing

- the array feature: `ARRAY`: planned, but not yet implemented.
- constants: `CSET`, `CSETQ`: planned, but not yet implemented.
- the compiler: `COMMON`, `COMPILE`, `LAP`, `OPDEFINE`, `READLAP`, `SPECIAL`, `UNCOMMON`, `UNSPECIAL`: not currently planned.
- property lists: `ATTRIB`, `GETPROP`, `PUTPROP`; these are planned, but not yet implemented.
- obsolete hardware related functions: `PUNCH`; not currently planned.
- memory debugging: `COUNT`; not currently planned.
- character I/O functions: `ADVANCE`, `CLEARBUFF`, `ENDREAD`, `INTERN`, `MKNAM`, `NUMOB`, `STARTREAD`, `UNPACK`; These are planned, but depend on working character I/O at Clojure level, which depends on JLine and looks like a lot of work.
- character classifying predicates: `LITER`, `DIGIT`, `OPCHAR`, `DASH`; these are planned but will probably wait for character I/O. Characters are not at this stage first class objects.
