It's a fun idea. I can see many usage. |
Try to introduce anonymous Struct literal.
${a:1, b:2} is equal to Struct.new(kw.keys).new(kw.values) where
kw is {a:1, b:2}.
If members of literal struct are same and same order, they share same class. Also fix ISeq#to_binary, .load_from_binary.

This seems unnecessary, because it is not a NODE_HASH.

${a:1, b:2}is almost equal toStruct.new(kw.keys).new(kw.values)wherekwis{a:1, b:2}.Anonymous class is prepared at compile time.
