Dcd autocompletion is not full

[Wusiki Jeronii]

Hello.
I use the VS Code. Autocompletion works. In logs, I see as DCD 
client and server works but a few commands aren't be suggested. 
For example, I see 'readln', 'writeln' and 'foreach', but, for 
example, loops declaration such as 'for', 'while' or 'if' 
statement and 'auto' type cannot be suggested by IDE. I don't 
think it is an IDE issue 'cause DCD runs. What the problem maybe 
is?
