Used during trace expansion; we will only consider expanding the trace from caller into callee if this evaluates to true. This can normally just be <code>equal</code>, but something fuzzier may be required if <code>t</code> is a type that contains identifiers from the caller/callee</p></dd></dl><dl><dt class="spec value" id="val-pp"
