sweet-expressions, and a simplified in-paren syntax — all thin the parens
without removing them.
** WAIT A lambda with a block cannot be a call's argument
On the author's decision. =sort-by(xs, fn(a, b)= plus a block is refused; the
lambda has to be bound first with =let=. Proposal: a call ending in =fn(...)= and a trailing =:=
hands the block to that lambda: =sort-by(xs, fn(a, b)):=.
** NEXT Lambdas are written with =>
Decided 2026-09-26: a lambda's body follows ~=>~, and ~=>~ is its only spelling
(~fn(a) = x~ is refused for a lambda; named functions keep ~=~). A header ending in ~=>~
takes an indented block even inside brackets, closing where the brackets close:
~sort-by(xs, fn(a, b) =>~ plus a block.
** NEXT A condition struct with a parent has no sugar
On the author's decision. =defstruct(DiskFull, :parent, IoError, [free i64])= is the fallback, with a
paren field vector. Proposal: =struct DiskFull :parent IoError= plus field lines.
** NEXT A type alias is written type Row = Vec(i32)
Decided 2026-09-26: .fln reads ~type Name = T~ as ~(defalias Name T)~, and the printer
writes it back.
** TODO flan check prints every definition of a file that checks
A clean =flan check= lists the whole prelude (about 170 lines). Clean should print
nothing, or only the file's own definitions behind a flag.
** NEXT Classes and methods have .fln syntax
Decided 2026-09-26: ~class Lambda(param, body, env)~, ~generic describe(v) -> dyn~,
~method describe(f: Lambda)~ plus a block (the class as the parameter's type),
~multi kind(v) -> dyn = type-of(v)~, ~method kind(v) when :int~ plus a block.
** NEXT A top-level let is a global
Decided 2026-09-26: in .fln ~let x = v~ at column 0 reads ~(def x v)~ and replaces
~def~, which is refused with that fix; ~once~ and ~const~ stay.
** NEXT A struct fits on one line
Decided 2026-09-26: ~struct Pt(x: i32, y: i32)~ beside the block form, like a data
case; union and a struct with a parent too.
** NEXT defmacro has no sugar
On the author's decision. =defmacro(repeat, [i n & body]):= with a space-separated parameter vector.
Proposal: =macro repeat(i, n, & body)= plus a block.

** CANCELLED Sugar for defclass, defgeneric, defmulti and defmethod
CLOSED: [2026-09-26]
The fallback, =defmethod(area, point, [p]):=, reads well enough.

** NEXT A dyn value takes .field and [:key]
Decided 2026-09-26: on a dyn value, ~x.name~ / ~(.name x)~ reads ~(get x :name)~ and
assigning it is ~(put x :name v)~ — a class slot or a map key; ~m[:k]~ indexes a dyn
map as ~(get m :k)~, and assigning it puts.
** DONE A slice from a C pointer, and a pointer cast
CLOSED: [2026-09-25]
=(slice-from p n)= and =((Ptr U) p)=, both unchecked. Rules out pointer arithmetic
