Richard Mann reports that
	$x = "black"; &bleach($x); print $x;
	sub bleach { local($x); $_[0] = "white"; }
prints "black" rather than "white".

This is the opposite of the old "variable suicide" problem.  Before
perl 3.042, the following
	$x = "black"; &print("white", $x);
	sub print { local($x, $y) = @_; print "$x $y"; }
would print "white white" rather than "white black".
