    Nicer soundness statements for the base_logic. · 473ad60b
    Robbert Krebbers authored
    This commit introduces the following soundness statements:
    
    - Soundness of pure propositions `⌜ φ ⌝%I → φ`.
    - Soundness of later `(▷ P)%I → P`.
    
    The old soundness statement, `(▷^n ⌜ φ ⌝)%I → φ` is now a derived form.
