<p>An implicit delimiter, that may, for example, appear around tokens
coming from a “macro variable” <code>$var</code>. It is important to preserve
operator priorities in cases like <code>$var * 3</code> where <code>$var</code> is <code>1 + 2</code>.
Implicit delimiters may not survive roundtrip of a token stream through
a string.</p>
