I should mention something less obvious as well: a declaration both
manipulates symbols known to the compiler, and usually causes allocation of
storage at runtime; and for classes, composition has runtime components.
Among other things that must be split between compile-time and runtime. So
it's no
Thanks Brandon for your answer. Yes, I agree that it makes sense that
declarations (and initializations) outside any sub should run before the
MAIN sub.
And I agree that we should probably avoid combining a MAIN sub with
non-declaring code. (And, as I said, I've never hit the case before because

The MAIN sub executes after the mainline.
After all should MAIN be called before or after do-it('2') in the following?
sub do-it(Str $string) {
say $string;
}
do-it("1");
multi sub MAIN() {
say "This is MAIN so this should print after the mainline";
}
do-it
Consider that "declarations" are actually executable code. They have
compile-time meaning, but many also have runtime meaning. This is most
obvious when it's a variable with an initializer: the initialization is at
runtime, not compile time. Which means MAIN has to run after all such, or
variables
Hi folks,
The documentation for the MAIN sub says that "the sub with the special name
MAIN is executed after all relevant phasers."
My understanding is that MAIN automatically executes before any code other
than phasers happening at compile time or at the end or right after the end
of compilation
