- A language construct I'd like to seeA new keyword: once<p>
This would be used in cases where you want to do something once, but not subsequent times the block is encountered. It could be for any language; I'm thinking C# at the moment.<p>
I run across this all the time:<p>
<blockquote>
<pre>
bool bPrintedHeader = false;
while (getSomeData())
{
if (!bPrintedHeader)
{
bPrintedHeader = true;
printHeader();
}
printData();
}
</pre>
</blockquote>
With once:<p>
<blockquote>
<pre>
while (getSomeData())
{
once
{
printHeader();
}
printData();
}
</pre>
</blockquote>
<p>Less code, easier to read, one less variable in scope outside the while. What's not to like?Thu, 01 Sep 2005 19:17:08 GMT
