returns the type(s) at compile-time. which is string or list of strings or a list of type expressions.
currently the string comes from the stash name, but in the future a type can also be an object (as in perl6), not a stash. the return value of typeof must be parsable as valid type declaration. so it should honor list context to listify | alternations.

similar to ref, which returns one run-time string, the current type. (but even if the value contains multiple types, only one is returned with ref).
but typeof gets the type from the OP*, not the attached SV*.

can it be indexed again i.e. in a variable declaration?

@vendethiel can you reformulate your question?

can you use typeof as the type of a variable?

Sure, that's the idea when using it with eval.

Note that you cannot do that with ref, but ref is only for introspection and was
not really carefully planned

Oops, thanks. I really should add support for functions also.

Encode 2.98
73802ce 
fixed some -Wsign-compare
See L<https://metacpan.org/changes/distribution/Encode>

Skip the flapping test F<t/Aliases.t> on threaded smokers, with random
segfaults.  This is a long standing core bug, with PMOP aliases or
clone. First observed at L<rurban/perl-compiler#73>
(since 5.6)

Stop directory tweaking C<$Encode::Encoding{utf8}>

Fix gcc warnings for older gcc < 4.0

Where possible do not depend on value of $@, instead use return value
of eval

Fix more XS problems in Encode.xs file

Load modules Encode::MIME::Name and Storable normally

Remove no warnings redefine; and correctly loaddependences

Remove PP stubs and reformat predefine_encodings()

Run Encode XS BOOT code at compile time

Use Encode::define_encoding and propagate carp/croak message

cperl fixes: encoding undeprecated, no strict hashpairs

Cleanup code for handling fallback/replacement characters

lib/Encode/MIME/Name.pm t/mime-name.t
Pulled: Add "euc-cn" => "EUC-CN" alias to Encode::MIME::Name
dankogai/p5-encode#124

lib/Encode/CN/HZ.pm lib/Encode/JP/JIS7.pm lib/Encode/MIME/Header.pm
t/decode.t
Pulled: Uninitialized value fixes #122
dankogai/p5-encode#122

Makefile.PL
Pulled: Fix -Werror=declaration-after-statement for gcc 4.1.2
dankogai/p5-encode#121

Fixed deep recursion in Encode::find_encoding when decoding.
