Oh All-knowing, All-seeing Trash Heap! :)

It is possible to use a TYPE when declaring a variable  my TYPE $a; ...

... but is it also possible to introspect this "type", kind of a $a->istype("TYPE") or $a->gettype() ?

my mentions fields but all I understood is that it's somehow deprecated since 5.8. (wasn't it meant for immutable hashes ...?)

What's confusing me is that neither ref nor reftype nor Devel::Peek show any signs of this typing, so it must be stored in fields somehow...

Bonus points if you can tell me:

Is it even possible to create compile time checks of types?

EDIT

I remember being capable to create errors after such "typing", but can't reproduce.
