<p class="commentary firstcommentary"><a id="SP7" class="paragraph-anchor"></a><b>&#167;7. The resolve halfopen blocks ramification. </b>At this point, all matching pairs of open and close braces have been removed.
But that doesn't quite solve the problem of code blocks, because an inline
phrase in Inform 7 can use the notations <span class="extract"><span class="extract-syntax">{-open-brace}</span></span> or <span class="extract"><span class="extract-syntax">{-close-brace}</span></span>
to indicate that a code block must be opened or closed, in a way which does
not pair up.
</p>
<p class="commentary">There is clearly no way for a tree structure to encode a half-open subtree,
so the schema itself has to have a special annotation made in this case, which
is done by calling <a href="2-is.html#SP5" class="internal">InterSchemas::mark_unclosed</a> or <a href="2-is.html#SP6" class="internal">InterSchemas::mark_unopened</a>.
It is inconvenient to delete the brace command node (we might end up with an
empty <span class="extract"><span class="extract-syntax">EXPRESSION_ISNT</span></span> list), so instead we convert it to a harmless piece
of white space.
</p>
<p class="commentary">At the end of this process, then, all code blocks are correctly handled, and
all statements are held as single <span class="extract"><span class="extract-syntax">EXPRESSION_ISNT</span></span> nodes. So the coarse
structure of the code is correctly handled &mdash; we have a clear tree structure
of statements (or expressions), hierarchically arranged in code blocks.
