Great. And for more fun I've created the basics of a NCI interface [1]
for ast functions. Heavily underdocumented and unfinished (as of an hour
hacking time ;-), but maybe someone takes it over and continues it. It
needs trunk rev 8598 for some added NCI signatures in src/call_list.txt.

It needs probably also a split into a "Past" and "Node" classes.
Compiling the resulting top node is also missing, but it should be quite
simple to either call the ast compile / emit functions with NCI or
create a better interface for that (I didn't look yet).

PS due to upcoming changes in parrot opcodes, you might avoid the
'compile' opcode. Instead:

   compi = compreg 'PIR'
   prog = compile compi, 'the_code'

the future is:

   prog = compi('the_code')

i.e. just invoke the compiler.
