They are and technically more so than what clang claims. The difference 
however is that dmd reports the error, while clang directs your attention 
to where you should proceed fixing the code. For trivial errors that does 
help, much like the spelling checker in dmd. 

These days I don't even notice it anymore that, whenever I encounter this 
error message, I mentally parse it as 'I missed something before line 5 now 
where is it...' 

>From the programmer p.o.v. the problem this message reports is almost 
always located in in the very last word of the dmd message even if 
technically it is not:

test.d(5): found '}' when expecting ';' following statement 
                                                    ^ you want to know this

Improving template related error messages however may give more bang for 
buck, dmd has already improved greatly in this respect and it really helps.
