<p class="purpose">Almost a Beatles song, but really a set of schemas for compiling the meaning of the unary predicates here, nowhere and everywhere.</p>

<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. </b>Here. In fact, at present "here" predicates are never included in propositions to
|
|
be compiled, so this code is never used. But the following would be correct if we

|
ever change our minds about that.
