... ongoing

o Typo and style fixes

... sometime in the future

o Change generic macro names (such as \table, \symstream, etc) to something more specific
o Add \bgrulealign and \egrulealign macros to align rules across sections
o Rewrite yytexlex.sty for better \TeX\ pretty printing macros
o Rewrite limbo.sty to provide a more logical structure
* Add indexing features to \TeXx macros (* there is a mechanism to do this)
o Change CWEB macros so that \pdfoutput=0 does not cause conflicts (this is a bug in cwebmac.tex)

... very remote future

o Make glr parser generation possible
o Make the `core' parsing and scanning macros prefix-expandable

... very very remote future

o Make automatic translation of \Cee\ into \TeX\ possible so that
  bison routines can be simply translated on the fly.
