What is the story behind the CRIMSON_SCOPE_HACK?
I see that it exists for each wheel, that it is meant to prevent SEGV's in
older versions of Perl, and that it appears to be used at the top of
anonymous subroutines passed as parameters to $kernel->state(...).
What older versions of Perl?
How does this prevent SEGV?
sub CRIMSON_SCOPE_HACK ($) { 0 }
....
sub {
# prevents SEGV
0 && CRIMSON_SCOPE_HACK('<');
# subroutine starts here
....
