What I can see now, mistakes are mostly syntactical like switch, auto, const, rebindable, array ops, full slice, arbitrary-code-contracts instead of single bool expression. Choice for round braces for templates leads to slightly unreadable template code: foo!(params params)(yet more params). Omissible parens feel like omissible semicolons :-/
Implicitly nested classes.
Versions should be typed variables.
C baggage is still around.
Extensive use of unsigned ints.
Well, I admit, properties are hard to get good.

Zealous backward compatibility with baggage, early desing and legacy code: these issues are no more fixable, I'm afraid.
