Any language that can interpret a turing machine can parse itself,
but do you want to? If I was writing a parser from scratch I would
use Griswold's Icon the new version is OO. But did these people write
the parser from scratch? I bet they started with a parser for some
other language and fixed it for ADA.

Would I want to write an ADA parser or any other parser in ADA? No!
No! 10^10^10 times No! But the customer might insist and I like to eat.
I'd like to write it in version 8 Icon, or Bison. C wouldn't be high
on the list either, it would be lower on the list than Ada which at
least has a garbage collector.

A computer language without garbage collection
