I'm not certain that plperl is actually correct to do it that way,
but that's the basic idea.
Why do we need the is_trigger flag at all for the plperl hash key? At
first glance it strikes me as unnecessary.
We might not. Does the presence or absence of the $_TD hash reference
have any impact on what we cache, or what Perl might cache internally?
For both trigger and non-trigger functions, we compile this ahead of the
user-set function code:
our $_TD; local $_TD=shift;
Non-trigger functions get passed "undef" to correspond to this invisible
argument, while trigger functions get passed the hashref that the
trigger calling code has set up.
