Hey all... I wasn't ignoring Jonathan's email, I just wanted to get to a state where I had more to say. So... to try to explain what I'm doing and the woes I'm running into, I should start at the start:
>From Rakudo, I'm trying to submit this PIR to Parrot: .local pmc value $P0 = loadlib 'BigInt' value = find_lex "$value" $I0 = value %r = new ['BigInt'] %r = $I0 That %r is the PMC that Rakudo reserves for return value from the PIR block. Some questions. First off, I'm getting this error: set_integer_native() not implemented in class 'BigInt' That seems absurd, and I'm sure I must just be misunderstanding something. Am I doing the assignment to %r (Rakudo's return value pmc placeholder, I believe) wrong? I get the same error if I define my own PMC for this, BTW. Second, my real goal is to figure out how to encapsulate a BigInt within a Perl class and then provide overloading for all of the typical Perl operations (arithmetic, conversion to Str, etc.). Is passing back a raw BigInt and then handing that around inside a an attribute the right way to do that, or is there some container I'm supposed to use for such purposes (preferably in any HLL)? Also, can I get access to all of the rest of what GMP is capable of from a BigInt? There's a lot of really cool stuff I'd like to export as methods on my BigInt class. Once I know these things, I can get back up to the level of dealing with things like I was describing in my original mail to perl6-compiler.
