Using

Description

Executes the expressions then runs the code within the statements and finally automatically runs unset() on each expression in the expressions list (Basically cleaning up after you).

using( <expressions> )
{
    statements
    ...
}

Parameters

expressions

A list of expressions to execute separated by ,

Remarks

None.

Example

Example on a simple string:

my $cat = "yyy"; // String exists
using( $cat ) // using will use the string
{
	println("str is: $cat"); // prints the string just fine
}
println("Final: $cat"); // nothing... the string no longer exists...

Example of using it with a class that will be deleted after the using block ends:

using( $newString = new CString("meow") )
{
	println("Hello world!: " . $newString);
}
// Immediately after the using block finishes the class gets unset() and its __Destruct will be run.

You can also stack them example:

my $cat = "yyy";
using( $cat, $newString = new CString("meow"), $coolstring = new CString("moo") )
{
	// the $cat and both class variables get unset once this block ends
}
