Since then, development of Flex has ceased - perhaps this might change
if it becomes a GNU project sometime. (There are different developers
for Flex and Bison.)

The Bison GLR parser, is written by Paul Hudak, and we discussed split
tokens, which it cannot currently handle, a bit on one of the Bison
lists (perhaps Bison Help).

But that was also some time ago, and there does not seem anything of
that going on now. The main focus is on computer languages, though it
would be nice to be able to experiment with natural languages.
