The `$` operator takes a sequence of FORMS and returns a unary
function which applies the input through that sequence via the `->>`
operator.
For example, consider the predicate "not null". `null` is built into
Common Lisp but "not null" requires writing a
function (lambda (x) (not (null x))). Now, using this operator, you
can write ($ not null) which returns the same lambda as above while
being more concise.
Splitting macros and functions into different packages and source code
makes it easier to look at. Functions currently implemented:
- range: like Python's range
- parse-integer*: parse-integer but junk-allowed is set to t.
`fn' is a convenience macro for defining functions with a type
specifier. Only really matters for `sbcl` and other hard-optimising
Lisp interpreters which actually take these seriously.
Setup boilerplate for system/package management. In particular, setup
an entry-point and Shinmera's "deploy" to build executables.
Also write some scripts to easily load or build the project without
Emacs - just `sbcl --load <x>.lisp`.
