FOREACH Loop Feature

Flow Control FOREACH Loop Feature

for, while, do while constructs work as they do in other languages. foreach is new.
If a solitary list is used then the loop control variable REFERENCES each value

Modifying the loop control variable modifies the list values!

@foo = ( "ape", "bat", "cat" );
foreach $animal ( @foo )
{
	$animal .= "-like";
}

Avoiding modification

@foo = ( "ape", "bat", "cat" );
foreach $animal ( @foo )
{
	$a = $animal;
	$a .= "-like";
}
