and the compiler, after upgrading to 2.082 from 2.080 now says:

when update is clearly a bool.
Why the hell is the compiler now thinking update is a void?
1. This code compiles fine in a test app and 2. when I rename
update to something else it works fine.
2. There is no other use of update in the entire module(not
that it should matter)
Seems this is a compiler bug but only has a problem in context.
Remember, it worked find before I updated dmd and there is no
reason why it shouldn't work.
- put
`pragma(msg, __FILE_FULL_PATH__ ~ "(" ~ __LINE__.stringof ~ "):" ~
typeof(return).stringof);`
in your update function.
- recompile.
- look at the compiler output
You should be sure at this point if the problem comes from your
update function of from the recent addition in object.d

Could you show some more code, as this works for me:
´´´
import std.stdio;
void main()
{
foo;
}
auto foo(bool update = false)()
{
static if(update)
{
}
}
´´´

I can't, the code is from a very large project and it's too
intertwined.
I already said it worked in simple form and that it worked with a
previous compiler, so this is a regression.
Changing no code and only swapping compilers produces this bug...
and as you can see, it's obviously a bug given the form of the
function and the error message and that it worked before without
changes.
Why the specific term update? I don't know.
My project does not use the term update at all in any other
context except that one. But I did find:
void update(K, V, C, U)(ref V[K] aa, K key, scope C create, scope
U update)
