Such functionality is not necessary. You could just make it an expansion
operator insted of variable. That would also give you the ability to
include arbitrary strings (such as message headers) in the hash, e.g.
with ${message_hash:$h_From:\n$h_Subject:\n}, which could return From,
Subject and body.
