Four features that justify a new Unix shell

OK interesting, I guess the question is if "use" requires running (not just parsing) arbitrary code? I guess if it's like Python's "import", it does.

Changing the grammar could still be considered static parsing, as long as the change doesn't depend on the values of variables at runtime, e.g. your argv array or something.

I recall Larry Wall saying that Perl 5 was at times confused about the language it was parsing, and the goal was to fix that in Perl 6. I don't have a lot of experience with it, but yeah that claim could be wrong, or at least un-nuanced.

The process of exporting symbols is done in an EXPORT subroutine that can be provided by the module developer. This subroutne is supposed to return a Map of symbol names and what they refer to. This Map can be constructed depending on external factors such as an argv array or an environment variable, although I have yet to see this in the wild.

So I guess one could say that Raku parsing is usually static, but it does not need to be.
