string s;

writeln(x)

and it worked as expected.  But:

string x = i"Message $(s) has value $(i)"

instead does NOT work.  And there's no toString, nor does 
to!string do the trick.  The core.interpolation file has no 
unittest, so I can't crib from anything there.  How _does_ one 
get the string post-interpolation?

This is with ldc2-1.40.0-beta4-linux-x86_64

Thanks,

i"..." returns a tuple of its constituents; to get a string, use .text.
Like this:

	import std;
	string x = i"Message $(s) has value $(i)".text; // should work
