I pointed one of my co-workers at Spark and he loved the lexer but said
that the parser ended up being too slow to be useful. I didn't know
enough about the Earley-algorithm to suggest how he could re-organize
his grammar to optimize for it. If naive Python programmers cannot
generate usable parsers then it may not be appropriate for the standard
library.
