<div class="desc"><p><code>a .. b</code> is a half-open numeric range used by the counting <code>for</code> loop: <code>for index in a .. b</code> walks <code>index</code> from <code>a</code> up to but <b>not including</b> <code>b</code>. This "up to but not including" convention makes lengths line up naturally — <code>0 .. len(route)</code> visits every element index of a slice, and <code>0 .. GRID_WIDTH</code> visits every column with no off-by-one. Both endpoints are <code>int</code> expressions, so a bound can be a <code>const</code>, a <code>var</code>, or any computed value. It is distinct from the string slice <code>text[start..end]</code>, which uses the same half-open idea for bytes.</p></div>
