Are messages passed to self() deep copied?

Questions / Help
1

Are messages that are passed from the current process to itself deep copied? For example, if a large non-binary data structure is sent between statem transitions, will that incur a copy or is message passing ‘smart enough’ to rely on using heap pointers?

2

Sending to self() is specially handled, so that the message will not be copied.
