Add inline slice preprocessor

The text `INLINE_SLICE(args, arguments)` will expand code which creates an
array `args` which is a safe copy of the arguments object. This should
be preferred over using `[].slice.call(arguments)` or any other direct
reference of arguments which causes allocation and possible leaking of
the object.
Remove commented out `logger` call
