Code:

----
import std.conv;
void main() {
   static assert(
     is(typeof(("Failure: " ~ to!string(55)) == string))
   );

   static assert(0 , ("Failure: " ~ to!string(55)));
}
----
main.d(7): Error: static assert  
['F','a','i','l','u','r','e',':',' ','5','5']
----

The problem is the ugly-ass "print as array of individual 
characters".

I really don't understand what is going on, since the compile 
type of my string is indeed "string".

If I remove the "to!string", I get:
----
main.d(7): Error: static assert  "Failure"
----

1) Is this the "normal" behavior, or a "known limitation"?
2) Is there a "workaround"?

FYI, this was originally produced by code from Phobos, but was 
trimmed by me here.

It seems a DMD bug, why don't you add it to Bugzilla?


 2) Is there a "workaround"?

static assert(0, text("Failure: ", 55));

"...Convenience functions for converting any number and types of

What is the "three character widths" note?
Who knows?

string, wstring, and dstring. Width refers to the bit size
of the char (8 bit, 16 bit, or 32 bit).

Thanks. I hope that will fix the Unicode ignorance of 'static assert' as 
well:

     static assert(false, "aüz");

produces the following output:

   Error: static assert  "a\xc3\xbcz"
