* improve M-C-f and M-C-b (they too often don't do the right thing) and
add M-C-k and other such sexp-chunked operations.
* if indentation is non-obvious, return a list of possible indentations
and choose the first unless the current is one of the possible choices.
* make `M-x sml-compile' more generic.
* allow specifying indentation of dependent keywords (how to indent `in'
relative to `let', for example).
* use symbols instead of strings for `sym'.
* ignore warnings in C-x ` ????
* recognize irrefutable patterns (with "Capital"-heuristics, for example:
a regexp like "\\([(),]\\|[_a-z][_a-z0-9]*\\)+").
This can then be used to allow indenting like
(fn x =>
some expressions)
* take advantage of text after-the-line (when available) for indentation.
* obey fixity directives.
* dangling `case e' in stuff like
fun myfunction x = case x
of bla =>
| bli =>
* deal with CPS kind of code ???
function1 (arg1, arg2, fn v1 =>
function2 (arg2, fn v2 =>
function3 (arg5, arg3, arg8, fn v3 =>
function4 (v1, v2, v3))))
or even just
F.LET (v1, foo,
F.LET (v2, bar,
F.LET (v3, baz,
F.RET [v1, v2, v3])))
