[nem-en] Known types from macroses problem.

[Ivan A Eryshov]

Guys,

macro.n:
<code>
	macro GetType()
	{
		def tp = "System.Int32";
		def nm = Name(tp);
		def ex = PExpr.Ref(nm);
		ex
	}

	macro GetType2()
	{
		def tp = "System.Int32";
		def nm = Name(tp);
		def ex = PExpr.Ref(nm);
		<[ typeof($ex) ]>
	}
</code>

test.n
<code>
	WriteLine(typeof (GetType())); // Error: 'GetType ()' is not a legal
type expression
	WriteLine(GetType2()); // Error: unbound type name 'System.Int32'
</code>

How to make this code working? Specially, I'm intrerested in working
2nd macro - GetType2.

Please advice.
