Eigenpoll : D wish list : Foreach on first/on last

To enable the coder to specify code statements that are only executed on the first and on the last iterations of a loop.

foreach( ; )
on first // First iteration only
on last // Final iteration only

Example:

foreach( CustRec c; CustomerList )
{
on first {
Lineno = 0;
Totals = 0;
Pageno = 0;
InitializeReport();
}

Lineno++;
GenPageHeading(Lineno, Pageno);
GenDetailLine(Lineno, c, Totals);

on last {
GenFooter(Totals);
CloseReport();
}
}

This is independant of the proposed 'else' clause.
