> There are no arrow operators in strings,

That's wrong! Variable interpolation does easily dereference hashes and arrays (i.e. within strings and substitutes).

DB<114> $h={a=>42} => { a => 42 } DB<115> "$h->{a}" => 42

Though coderefs seem to be excluded.

DB<118> $sub=sub { "nope" } => sub { "???" } DB<119> "$sub->()" => "CODE(0xa5cc200)->()"

But the @{[...]} ("local eval") trick always helps where a general /e would cause too much harm.

DB<120> $_="X" => "X" DB<121> s/X/@{[ $sub->() ]}/ => 1 DB<122> $_ => "nope"

see also: s/RegEx/substitutions/: Variable interpolation and when to use /e - modifiers
