Some parts of the language are not discussed in the tutorial

[peterohanley]

• cn_function
• pack
• bitwise functions (operators are not present in the logical language)
• instantiate ("extract for pure quantifiers")

[bcpierce00]

I've made a note of these at the end of tutorial.adoc

rems-project/cerberus#230 (comment)

Just adding here so that it's logged somewhere. You can also have arguments, but the most common case is for constants.

And this (MIN/MAX{u,i}{8,16,32,64})...

It's possible sometimes to write Owned(p) instead of Owned<...>(p) but this is only used in a malloc example, never explicitly mentioned.

I also don't see any mention of instantiate in the tutorial. It turned out to be necessary for a spec that I wanted to write, which I hope to include in the archive via #49. That example turned out to be a good way for me and @septract to learn about the semantics of instantiate - perhaps it (or something like it) would be a good addition to the tutorial as well.

[bcpierce00]

Would you be willing to write up the example in the style of the tutorial and add an exercise or two (or three) to give readers a chance to try it out themselves? (Just bullet points is fine if you are pressed for time, but it's really helpful to capture the experience of "oh, here's what I would have needed to be explained to understand how to use this for what I wanted..." from the inside!)

Sure, I'll do that.

[septract]

We have now disabled pack / unpack, and declared cn_function experimental. So I don't think we need to discuss them in the tutorial.

This still leaves bitwise functions and instantiate.
