[P4-dev] Suggestion: Adding sizeof

While P4's lack of void* all over the place makes the sizeof() operator
known from C not absolutely necessary, I believe it could still be useful
to have it. For example, the protocol I am currently parsing likes to
specify offsets and align things to 8 bytes. Therefore I am finding myself
writing a lot of header definitions followed by `const int my_header_size =
...`. This feels very wrong to me. Unless I am the only person in the world
who needs that, I think adding sizeof() to the language in some future
version might be useful.
Thanks, and best wishes,
