Version Used: .NET 8.0.201

Hello, everyone! I've noticed a really strange behavior from the compiler. It occurred when I used a simplified using statement that looked like this:

using const var obj = new Object();

The compiler didn't flag any errors as it should have. It's strange because with the normal version

using (const var obj = new Object())

the compiler correctly flagged a "CS0822" and a "CS1525". It's as if the compiler ignores errors in simplified using statements.

Expected Behavior:
The compiler should flag a "CS0822" and a "CS1525".
Actual Behavior:
The compiler doesn't flag any errors and when you try to build the application, it finishes with:
(Visual Studio)

MSB6006 "csc.exe" exited with code -2146232797.

or
(Visual Studio Code)
