class vector {<br />
public:<br />
// purposefully not doing reference <strong>here</strong>...<br />
T oper<strong>at</strong>or[]( size_t i ) {<br />
return d<strong>at</strong>a_[ i ];<br />
}<br />
// other things<br />
priv<strong>at</strong>e:<br />
T * d<strong>at</strong>a_;<br />
};<br />
If T = bool, we are wasting an entire byte on th<strong>at</strong><br />
boolean value (which can, in theory, be represented as a<br />
single bit)<br />
We want to special case, or specialize on T = bool to<br />
change the default behavior <strong>of</strong> the class!
