<p class="purpose">To alphabetise literal texts, deduplicate them, and store a canonical set in the synoptic/texts submodule.</p>
<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. </b>Before this runs, literal text constants are scattered all over the Inter tree.
At the end, they are all moved into a submodule of the synoptic module called
<span class="extract"><span class="extract-syntax">texts</span></span>, and are presented in alphabetical order (case sensitively) without
duplicates.
</p>
<p class="commentary">This is not done to save memory, though it does that too, but because we want
runtime code to be able to compare literal texts by performing an unsigned
comparison on their addresses. The following works:
</p>
<pre class="displayed-code all-displayed-code code-font">

</pre>
<p class="commentary">because the two instances of <span class="extract"><span class="extract-syntax">"Rhayader"</span></span> compile to the same data in memory.
Dynamic texts must of course be compared more expensively.
</p>
<p class="commentary">This cannot be arranged in the main body of the Inform compiler because these
two instances might be much further apart than in this example &mdash; one might be
in a kit, and the other in an unrelated extension, say.
</p>
<p class="commentary">Our inventory <span class="extract"><span class="extract-syntax">inv</span></span> already contains a list <span class="extract"><span class="extract-syntax">inv-&gt;text_nodes</span></span> of constant
definitions whose value is a literal text.
