The following code produces an unexpected compile error:

private import std.string;

void main()
{
std.string.toString(cast(dchar)'a');
}

test1.d(135): function std.string.toString called with argument types:
(dchar)
matches both:
std.string.toString(char)
and:
std.string.toString(creal)


¿creal? ¿Why does it match creal?

This error message is quite confusing.  It's because there is no toString() 
overload for wchar or dchar.  You have to cast to char to use toString.

I don't really get why it thinks creal is a match, though.
