Re: Past-pm basic string types
Patrick, what's the best way to pass-through string types from a
compiler to Parrot without doing full string processing? To pass the
current tests, Punie only needs Parrot's single- and double-quoted
strings, but Past-pm is escaping them. So:
print "\n";
reaches the PIR translation as:
print "\\n"
(I will add full string processing to Punie later, but since other
compilers will also need basic Parrot string types, it makes sense to
figure it out now.)

In Punie or Perl 6, when I execute a simple statement:
print "2";
It prints "21". This is because a) the return value of a successful
print is "1", b) the main routine is returning the value of the last
statement (note this is correct for Perl, but isn't correct for all
languages), and c) HLLCompiler is printing out the return value of the
eval'd code here:
376 save_output_1:
377 print ofh, result
378 close ofh
Commenting out line 377 gives the correct behavior of just printing "2".
My question is, why is HLL compiler printing out the return value of the
main routine?
