The byte code output is now interleaved with the generated machine code on selected architectures. o Complain about redundant backslash escapes. o '__weak__' modifier added. It is now possible to declare object variables to have weak references.
o Support for arguments to implicit lambdas added.
Implicit lambdas now behave as if they were declared as
lambda(mixed ... __ARGS__).
o Function local function declarations are now statements (and not expressions). This means that there is no longer any need to terminate them with a semicolon. o Complain about shadowed variant functions. o Machine code support for more architectures. There's now machine code support for arm32 and arm64.
