As other have said, typeglobs are globals. If you're comfortable with that, then this will get you started on how to assign to, and dereference them:
our *a = \25; *a = [1..10]; *a = { 'a'..'z' };;
printf "Scalar:%s\nArray:[ %s ]\nHash:{ %s }\n", $a, join(',', @a ), j
+oin('.', %a );;
Scalar:25
Array:[ 1,2,3,4,5,6,7,8,9,10 ]
Hash:{ w.x.e.f.a.b.m.n.s.t.y.z.u.v.c.d.k.l.q.r.g.h.i.j.o.p }
printf "Scalar:%s\nArray:[ %s ]\nHash:{ %s }\n", ${*a}, join(',', @{*a
+} ), join('.', %{*a} );;
Scalar:25
Array:[ 1,2,3,4,5,6,7,8,9,10 ]
Hash:{ w.x.e.f.a.b.m.n.s.t.y.z.u.v.c.d.k.l.q.r.g.h.i.j.o.p }
Of course, that's only three of the six things that can live in a typeglob; but I'd have to look the others up as I've rarely used them.
If you want the full skinny on them, see MJD's page on them.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
In the absence of evidence, opinion is indistinguishable from prejudice.
