Why not use LPeg?
-----------------
The use of a custom parsing library boils down to two reasons:
1. LPeg can't stream or produce partial outputs. This just makes it difficult to use for making a compiler.
2. LPeg can't process tables. It's still possible to use LPeg to parse table-based structures, but one must serialize them beforehand, which is... far from ideal, to say the least.
