I'm not sure what you mean here by "two instances of the Perl parser". I'm pretty sure I know what you're getting at, but I wouldn't call it two instances of the parser. It is more like two possible syntactic interpretations/parses of the same piece of code, depending on the prototype of a previously defined sub.

in thread Perl is not Dynamically Parseable
Saying "two instances of the parser" produce different things (on the same given code, presumably) makes it sound simply like the parser is non-deterministic or randomized.
