[DGD] Switch-Case Variable Scope

[Kris Van Hees]

Why would you not simply use:

	switch typeof(arg)) {
	    case T_ARRAY: {
		mixed *ret;
		<code>
		break;
	    }
	    case T_MAPPING: {
		mixed *ret;
		<code>
		break;
	    }
	}

A case label does not establish a local scope sice it is not a statement block,
but it is very easy to encapsulate the statements in a statement block, and
thereby gain local scope to do what you want.  No need to change the language
syntax for that...

	Cheers,
	Kris

 - the Intelligence to cast Magic Missile,
