It was pointed out that Coq already uses `now` for a different kind of tactic.
And `done` is more descriptive anyway.

feat(library): instances are not reducible by default anymore
...
Motivation: see "Other goodies" section at
https://github.com/leanprover/lean/wiki/Refactoring-structures
We had to add a new transparency mode: Instances at type_context.
In this mode, instances and reducible definitions are considered
transparent.
The new mode is used in the defeq_canonizer, code generator,
and sizeof lemma generation at inductive_compiler.
We also use the new mode in the unfold tactics.

fix(library/init/meta/tactic): use zeta reduction by default in the abstract tactic
...
Abstracting let-exprs may produce type errors.
In the future we may consider another strategy for `abstract`.
First, we try to abstract the `let`, then if it fails, we expand.
Not sure if this is a good idea.

feat(frontends/lean/elaborator): coercion from (decidable) Prop to bool
...
This is a hard coded extra case. It is not an instance of has_coe.
Even if we change has_coe to accomodate this case, it will not be a
satisfactory solution because this coercion depends on the element and
not the type, and the element usually contains metavariables.
We should eventually write a tactic for synthesizing coercions.

refactor(library/init/meta): avoid '_core' idiom using default parameters
...
I kept a few core methods (e.g., exact_core and apply_core). Reason:
if we use default parameters
meta constant exact (e : expr) (md := semireducible) : tactic unit
then, we will not be able to write
to_expr p >>= exact
The workaround is
do t <- to_expr p, exact t
or
to_expr p >>= (fun x, exact x)
One alternative is to change how we handle default parameters, and
eta-expand applications that involve default parameters.
We may also have an attribute [eta_expand]. Then
attribute [eta_expand] foo
instructs the elaborator to automatically eta-expand foo-applications.
The attribute would give users more control, and avoid potential
performance problems. Without the attribute, then for every function
application the elaborator has to check the type and decide whether it
must be eta-expanded or not.
