feat(frontends/parser): simplified theorem definition using tactical proof When using tactics for proving theorems, a common pattern is Theorem T : <proposition> := _. apply <tactic>. ... done. This commit allows the user to write the simplified form: Theorem T : <proposition>. apply <tactic>. ... done.
