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?

Well is kinda sounds right, complex numbers are twice as big as reals and have the letter ‘i's in them. ;)

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.
