+ portability:

- port ffi to win64
- update amd64 for %unbox-struct and callbacks
- get factor running on mac intel

+ io:

- if select() returns an error, fep
- stream server can hang because of exception handler limitations
- better i/o scheduler
- if two tasks write to a unix stream, the buffer can overflow
- out of memory error when printing global namespace
- "localhost" 50 <client> won't fail

+ objective C/cocoa:

- CFBundle error handling
- autoload frameworks in cocoa class words
- exceptions
- subclassing
- messages returning structs by value
- fix bootstrap compile errors
- super message sends

+ ui/help:

- make the UI look better, something like this:
  http://twb.ath.cx/~twb/darcs/OBSOLETE/factor/final.html
- fix remaining HTML stream issues
- UI browser pane needs 'back' button
- fix up the min thumb size hack
- help cross-referencing
- document FFI
- document tools
- document conventions
- new turtle graphics tutorial
- better line spacing in ui
- use vertex arrays and display lists to speed up ui
- tabular formatting
- don't multiplex in the event loop if there is no pending i/o

+ compiler/ffi:

- float intrinsics
- complex float type
- complex float intrinsics
- out of memory from ffi calls
- out of memory from overflow check
- remove literal table
- callbacks
  - input values which get spilled
  - value type struct inputs
- exceptions inside callbacks are broken:
  - we need to unwind the stacks to the level where the exception handler
    was set
- ffi unicode strings: null char security hole
- utf16 string boxing
- signal handler should not lose stack pointers
- FIELD: char key_vector[32];
- FIELD: union { char b[20]; short s[10]; long l[5]; } data;
- MEMBER: long pad[24];
- C structs, enums, unions: 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
- clean up C stack frame assembly code to avoid moving spilled arguments
  twice

+ misc:

- code walker & exceptions
- slice: if sequence or seq start is changed, abstraction violation
- delegating generic words with a non-standard picker
  - pass an integer stack pos instead of a quotation
- make 3.4 bits>double an error
- colorcoded prettyprinting for vocabularies
