And then with B<Acme::FSM::Tiny> with run time checks stripped.
Also, see L<B<BUGS AND CAVEATS> later in this POD|/BUGS AND CAVEATS>.

=head2 Concerning Inheritance

Through out code only methods are used to access internal state.
Supposedly, that will enable scaling some day later.
The only exception is L<B<connect()>|/connect()> for obvious reasons.

Through out code neither internal state nor FST records are cached ever.
The only one seamingly inconsistent fragment is inside main loop when next
I<$state> is already found but not yet entered.
I<$action> is processed when the next I<$state> is set
(though, in some sense, not yet entered).
(If it doesn't make sense it's fine, refer to
L<B<process()> method|/process()> description later in this POD.)

This notice seems to be useles.
Instead, it might come handy someday.

=cut

lib/FSM.pm  view on Meta::CPAN

It's not hard to imagine application of rather limited turn map that should
default on anything else deemed irrelevant.
Right now to achieve logic like this such defaulting ought to be merged into
B<switch()>.
That's insane.

=item Diagnostics

B<(misdesign)>
Mechanics behind diagnostics isa failure.
It's messy, fragile, misguided, and (honestly) premature.
At the moment it's useless.

=item Hash vs HASH vs Acme::FSM Ref Constructors

B<(messy, probably bug)>
L<B<connect()> method description|/connect()> _declares_ that list is copied.
Of course, it's not true deep copy
({fst} might contain CODE, it's not clear how to copy it).
It's possible, one day list trailer variant of initialization may be put to
sleep.
