Incluso

The incluso is the opposite of a proviso.

A proviso may be a ginger, lilly-livered construction, but at least it does something: it takes a stated general principle and weasels out of it.

The promisor herewith agrees to pay, inconditionally and in full, all amounts due, provided that on no account shall the promisor be liable for: ... [here follows a catalogue of exceptions great and small the sum total of which will equal, or perhaps even exceed, the value of the commitment so generously given].

An incluso states the general principle, and then illustratively repeats it, bearing useful confirmation only to those afflicted by profound ontological uncertainty as to whether you meant what you just said in the first place.

We will send such confirmations and information in such form (including paper, writing, parchment, scrolls, hand-signals, facial tics, morse code, semaphore, maritime signaling systems or other symbolic language (whether carried out with or without the aid of flags) as we shall determine from time to time.

A well crafted incluso will drag into contemplation items which no ordinary reading of the general principle could possibly have anticipated.

The sign of a true legal master is the provuso, which is an amalgam of a proviso and an incluso.

This states a general principle, then caveats it so comprehensively that the final provision means the opposite of the notional proposition.
