$ra is a scalar that holds a reference to an array. $ra->[0]
dereferences an array element. To dereference an array slice use:
@{ $ra }[ 0, 1, 2 ]

@{ $ra }[ 0 .. 2 ]

Yup:
http://www.perlmonks.org/?node_id=80399
ok 7 - @{$ra}[0, 1, 2] a b c
ok 8 - @{$ra}[0 .. 2] a b c
ok 30 - @{fra()}[0, 1, 2] a b c
ok 31 - @{fra()}[0 .. 2] a b c
ok 42 - @{$oa->ra}[0, 1, 2] a b c
ok 43 - @{$oa->ra}[0 .. 2] a b c
The other issue was "Ambiguous use of @{fra} resolved to @fra" (tests 28
and 35). The solution is to put "+" in front of the function name:
ok 28 - @{+fra} a b c d e f
ok 35 - @{+fra}[0, 1, 2] a b c
Thanks!
