in reply to [Parrot] tracing method calls

I'm just learning the code base ... which is an odd position for a Fearless Leader ("OK, Mr. President. You've been elected by this country ... no, the top of the globe..."). But it looks to me like to do what you want without writing a bunch of explicit wrappers, until we have a PerlObject PMC that implements AUTOLOAD which could handle it, you'll have to write a PMC of your own.

I'll call this new PMC ObjectWrapper. Give ObjectWrapper a customized find_method() vtable function that always returns your chosen wrapper function, which can do whatever recording you like then look up the actual method by name in the actual target object.

This is all pretty much the way it should be, except (1) we will have autoload-ish behavior available in a standard PMC eventually, and (2) there's no reason this sort of custom behavior should require writing in C anyway. Eventually. :-,

[Eily]: Just another Perl coeurs
[Eily]: (perl with hearts, 'Acker with a French accent is pronunced like coeurs)
[LanX]: IMHO 'ju' for 'u' happens in English where they can't pronounce the French u (or German )
[LanX]: and I'm sure I read that *hotel* used to be pronounced 'otel by the English upperclass
[Your Mother]: American English vowels are pretty lazy/mumbly in general.
[LanX]: talking about antisemitism, youtube automatic subtitles is entertaining shocking sometimes ... like when offering "Fruit Jews" as a drink
[Your Mother]: ...Come on you King of the Juice...
