and the compiler, after upgrading to 2.082 from 2.080 now says:
Error: expression `update` of type `void` does not have a
boolean value
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.
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)
{
}
}
´´´
compiled with
dmd --version

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)
