bf583f6065 chore: add placeholders for mkInjectiveTheorems 
We can activate them yet since the method is failing when there are
heterogeous equalities in the injectivity theorem type.

be841a7cad chore: throwError! => throwError, throwErrorAt! => throwErrorAt 
@Kha I marked the corresponding methods as `protected`.
I currently can't stand `throw_error`, and I am optimistic about
server highlighting feature you are working on :)

68143ca8ba chore: trace[...]! ==> trace[...] 
@Kha I think this one is a good change, there is no real reason for
using the `!` suffix here.

729047b5a2 feat: auto bound implicit at constructors 
@Kha This commit adds auto bound implicits to constructors.
I was excited until I tried to define the `Bigstep` type again without
`autoBoundImplicitLocal`, and found small typos.
Example, I had
```
  | ifTrue  : eval σ₁ b = true  → Bigstep (c₁, σ₁) σ₂ t → Bigstep (cond b c₁ c₂, σ₁) σ₂ (t₁ + 1)
```
where `t₁` should be `t`, but the declaration was accepted. I am
wondering whether Isabelle performs some kind of sanity checking,
and/or enforces rules such as: auto-bound implicits may only be
introduced by hypotheses.
Note that this is not an issue for definitions, because the body of
the definition will probably not type check when we have this kind of
typo in the header.
Anyway, I am putting the experiment in this branch for now.
That being said, the `Bigstep` declaration is way nicer with
`autoBoundImplicitLocal`s.

Another option is to add a new option `ctorAutoBoundImplicitLocal`
that is false by default, and activates auto implicit locals for
constructors when set to true.

d6f778bec4 refactor: arbitrary without explicit arguments 
@Kha I was tired of writing `arbitrary _` :)
There 0 places in the stdlib where the type needs to be provided.
If in the future we need to specify the type we can use
`arbitrary (α := <type>)`

c9cbe35916 fix: adjust code to optional , at structure instances 
@Kha I implemented the optional `,` at structure instances.
You have suggested it a few weeks/months ago. F# also implements this
feature. I got back to it while write documentation for Lean.
It looks quite nice when we are packing many functions into a structure.

BTW, F# also has optional separators for list literals :)
This is a much simpler change for us since `[...]` is defined using
the `syntax/macro_rules` commands, but I didn't find optional ','
would very useful since our list literals are usually in a single
line.
