76799db032 feat(library/init/meta/interactive): simph ==> simp [*] 
This modification was suggested by @kha.

TODO:
- Use `simp [-f]` instead of `simp without f`
- Allow users to remove hypothesis from `*`. Example: `simp [*, -h]`
  for simplify using all hypotheses but `h`.

87932f1c56 feat(frontends/lean): change notation for inaccessible patterns 
The following are accepted
 .(t)
 ._

We don't accept .t anymore because it will conflict with the field
access notation.
