What happens with the types of data during an assignment is a matter for
language design, not for internals. It can (and should) go either way
depending on how the parser spits out bytecode.
Both ways are perfectly correct. The only question is which way it should
go. (Or, knowing Larry, which data type is tighter binding or something of
the sort)
