The point is the error message should not expose mangled name to users. The
original title is pretty clear.

I'm confused. Since when has it been legal to pass a type as a function
argument?

It's not legal. I was just explaining the error message of this bug:
import std.string;
void main()
{
char[] s= string.format("abc","abc");
}
testd.d(5): Error: cannot implicitly convert expression (format((&
D20TypeInfo_B9AyaAyaAya6__initZ),(immutable(char)[]),

Version|2.028 |1.043
Summary|Weird message with cryptic |Weird implicit conversion
|mangled name - implicit |error with cryptic mangled
|conversion error |name - assigning to invalid
| |arraytype.function call
So the bug is that it tries to make out the type of the expression and gets
somewhere (and hence delivers an error) before realising that string.format is
itself invalid.
The bug also occurs in DMD 1.043, as this shows:
----------
import std.string;
void main() {
int s = string.format("abc", "def");
}
----------
array_static_method.d(4): Error: cannot implicitly convert expression
(format((&
D17TypeInfo_B6AaAaAa6__initZ),(char[]),"abc","def")) of type char[] to int
----------
Strangely, given (int[]) instead of string, 2.030 gives an almost identical
cryptic message, but 1.043 emits the more sensible
----------
array_static_method.d(4): Error: no property 'format' for type 'int[]'
array_static_method.d(4): Error: function expected before (), not 1 of type int
----------
(OK, so the second message is bogus, but that's just a case of a long-known
issue.)
