I am a Parrot core developer who just recently learned about Neko. I

question:
<snip>
I do not know much about Parrot, so the following is the only question I
can really answer...
4) Parrot is written in C while Neko compiler is written... in Neko.
This is also blatantly false. Neko *does* have a core written in C,
just like Parrot. As much as Neko as possible is implemented in Neko,
and the same goes for Parrot. Parrot is actually written in
"C-with-sugar" and there is a build subsystem (written in Perl 5)
which translates this "C-with-sugar" language into pure C. Parrot also
uses NQP heavily to do parsing, i.e. transforming source to Abstract
Syntax Trees. Also, many Parrot subsystems are pure (or mostly) PIR,
such as our testing framework, test_more.pir . We do have some tests
in Perl 5, but they are being transitioned to PIR
I hope this isn't splitting hairs too finely, but what it says is that
the Neko _compiler_ is written in Neko (actually NekoML, I believe). The
VM is certainly written in C.
