Non-existing reserved words, variables and functions are not flagged as errors.

Hello, I have detected a problem or detail that makes me late to find out about certain errors: I'm not sure if it's my computer, but I tried it on two computers I have with different operating systems (Windows and Linux), and it's exactly the same. When I develop with VSCode and Dlang (with the Dlang extension), I have sometimes had errors when compiling because I mistype a variable, function, reserved word, and the LSP doesn't mark it as an error and I have to notice it when compiling. I tried to see if the same thing happened with typing non-existent functions and reserved keywords, and indeed, it doesn't mark them as errors.
