Re: Should this be flagged as a warning?

Bernard Helyer:

    match(ts, TokenType.Is);
    match(ts, TokenType.OpenParen);
    isExp.type == parseType(ts);
The bug being of course, that a type is parsed and ts is 
modified, so the expression has side effects so it's not
flagged as a useless expression. But the comparison still
has no effect, so should this be flagged by DMD?

The top level operation is the ==, that is a pure expression, so 
maybe dmd should warn on this.
