Chris Double 4e29081e93 Make left recursion in pegs a failed parse
Eventually left recursion will work fine, but this is prevents an infinite loop for now.

Chris Double 85a3ee3e5b Remove memoization in 'compile' word in pegs
This creates issues when recompiling a an existing EBNF parser for reasons I've not yet tracked down. Disabling it slows things down but makes things work correctly till I investigate the issue.

Chris Double 943b02ab2f Fix performance regression in pegs
delay parser is improved to use a memoized quotation so the
construction and compilation of the parser at runtime only
occurs once.
Changed compile so it would use equality rather than identity
for memoization purposes.

Chris Double 1c6882b32c Rip out packrat stuff
It was broken since the transition to generating compiled quotations. As far as I know, no one was using packrat-parse anyway.
Rework in progress...
