1- normal switch => switch statement
2- normal switch => switch statement in code gen
3- for null checks: ReferenceEquals(...) to pattern (x is nully is not null) applied in code gen
4- use range operator instead of "string".SubString(...); ("string"[x..y] or "string"[x..] or "string"[..y]) or "string"[x..^y])
