They are a bad design choice. Using very shortened 
identifiers/names is acceptable only when they are very common 
(time ago I even suggested in D to use "str" as in Python, 
instead of "string"). "mut", "pub", and "priv" optimize the wrong 
thing.

There are of cases where D goes too much far (like 
"std.random.randomShuffle" or "schwartSort" in Phobos, or 
"immutable" among the keywords) but in general the naming choice 
of D is better than Rust.
