# Send is so complicated that we actually code it in ruby and stick it in
# That off course opens up an endless loop possibility that we stop by reducing to Class and Module methods

# Note: I find it slightly unsemetrical that the NewMessage object needs to be created before this instruction
# This is because all expressions create a (return) value and that return value is overwritten by the next
# expression unless saved. And since the message is the place to save it it needs to exist. qed
