Out of those: iteration.
I agree this is important. I've been implementing the "Shootout"
programs in Kawa, and having to use do or named-let is OK, but
rather verbose and klunky.
It also is holding up my writing of the Kawa tutorial - I'd like to
use something more "list-comprehension-like".
At least something like Common Lisp's LOOP or
ITERATE. Ideally something like SERIES[1] (with loop fusion for nested
series expressions) combined with a terse comprehension syntax for the
common case (i.e. map+filter+reduce).
I certainly much prefer series over loop/iterate.
I have a rather radical design that I'll talk more about
after I get 1.11 out the door.
In general, make Kawa more "friendly", e.g. add doc-strings, make it
easy to find the source file of functions, add an object inspector etc.
I think many of these are IDE issues, though I realize traditionally
IDE's in Lisp have depended on eval and repl. Thus I don't think
old-fashioned docstrings (in the sense of a run-time property)
is really the right thing. Better an annotation (or a separate
resource file), so the strings can be found either at compile
time *or* at run-time.
[OTOH, to become "rich and famous" you should probably do something
related to parallelism and/or cluster/cloud computing :-)]
Part of the plan/goal for a "list-comprehension" is to optionally
implement it like a "ParallelArray". More later ...
