The script is in tools/ rather than thrown away, because two lanes are
writing Flan in the old spelling right now and their files need the same
pass at merge.
It works on forms, not on text: a keyword becomes a dot only where it sits
in a field-label position inside a brace, so an enum member in value
position, a map key inside an EDN string and a type-position {K V} are all
left alone. :keys keeps its colon -- it names no field.
print and println had no line anywhere on index.html — a builtin the reader
meets in the first example and is never told about. There is a section for
them now, between arrays and the prelude: what the walk covers, that an enum
comes back as its name and a Ptr does not get followed, that a string is raw
at the top and quoted inside a structure, and that the depth and span caps
are what keep a grid from printing a screenful. printing.flan is beside the
other examples so check.sh has been green on every line of it.
The prelude's table loses its output row, because the prelude has no output
functions left, and the fifty-odd example blocks follow the files they quote.
Two pinned things moved. sand-headless prints 15595743031174623232 where it
printed -2851001042534928384: same bits, read unsigned, because the cast that
made it signed is gone. bounds.flan's trap moved from column 28 to 19, which
is where (at xs i) now starts on that line.
And the indirection-cell illustration is defer.flan rather than hello.flan.
hello.flan cannot show a cell any more: its one call was to a prelude
function, and println is compiler-provided, so the smallest program makes no
Flan-to-Flan call at all. defer.flan's main calls work, and is already on the
page a few sections up.
