Interesting. It should certainly save Tom a lot of work, but might
also have
some real-world application.
I can attest to that. I'm developing a Unix layer for classic Mac OS
called Lamp (Lamp Ain't Mac POSIX). I've been able to borrow some of
the key header files from Matthias Neeracher's GUSI project (a Mac
sockets implementation also used in his MacPerl port), but I don't
have a full Unix libc, which makes compiling certain tools (like most
shells) problematic.
So I've had to write my own. It's far from complete -- it does what
I need it to, right now, but it's not going to run any configure
scripts any time soon. A conforming sh (even as a Perl script) would
be very useful to me (provided it's pure Perl, since I haven't
implemented dlopen() yet).
I'm probably just going to translate the C line-by-line at first--a
more elegant solution can be taken care of later.

It's also easier to write the shell from scratch, based on some of
the scripts I've seen...
Maybe after that I can do a C-to-perl compiler ;)
How about a C compiler for Parrot?
