0.81:

- x11 title bars are funny
- amd64 %box-struct
- automate .dmg build, put sources there
- defining methods returning structs in objc

+ portability:

- win64 port
- get factor running on mac intel
- amd64 %unbox-struct
- when generating a 32-bit image on a 64-bit system, large numbers which should
  be bignums become fixnums

+ io:

- httpd fep
- stream server can hang because of exception handler limitations
- better i/o scheduler
- yield in a loop starves i/o
- "localhost" 50 <client> won't fail

+ ui/help:

- help search
- reimplement clicking input
- reimplement tab completion
- x11 input methods
- cocoa:
  - global menu bar with useful commands
  - expired aliens in view hash
  - don't multiplex in the event loop if there is no pending i/o
  - horizontal scrolling
- fix mouse-overs...
- clicks sent twice
- speed up ideas:
  - only do clipping for certain gadgets
  - use glRect
  - display lists
- saving the image should save window configuration
- make the UI look better, something like this:
  http://twb.ath.cx/~twb/darcs/OBSOLETE/factor/final.html
- fix remaining HTML stream issues
- fix up the min thumb size hack
- automatically update help graph when adding/removing articles/words
- document conventions
- new turtle graphics tutorial
- better line spacing in ui and html
- tabular formatting - for inspector, changes and $values in help
- grid layout
- variable width word wrap
- fix top level window positioning
- changing window titles

+ compiler/ffi:

- remove <char*>, <ushort*>, set-char*-nth, set-ushort*-nth since they
  have incorrect semantics
- can <void*> only be called with an alien?
- core foundation should use unicode strings
- improve callback efficiency
- alien>utf16-string, utf16-string>alien words
- float intrinsics
- complex float type
- complex float intrinsics
- out of memory from overflow check
- remove literal table
- C functions returning structs by value
- FIELD: char key_vector[32];
- FIELD: union { char b[20]; short s[10]; long l[5]; } data;
- MEMBER: long pad[24];
- C structs: use new-style string mode parsing
- [ [ dup call ] dup call ] infer hangs
- the invalid recursion form case needs to be fixed, for inlines too
- code gc
- compiled gc check slows things down

+ misc:

- clean up stack effect generation code
- code walker & exceptions
- slice: if sequence or seq start is changed, abstraction violation
- make 3.4 bits>double an error
- colorcoded prettyprinting for vocabularies
- signal handler should not lose stack pointers
- code walker and callbacks is broken?
