Description: "uint i = -1" is allowed by dmd 1.050. 
Expectation: A warning or an error should be shown by compiling the code.

I misspelled int as uint. A boolean expression (if i < 0) always equals false.
It took me long time to debug my code. Finally I have found out, that the value
i is not -1.

I'll put this as an enhancement request because negate is currently an
operation that is defined to work on unsigned values, hence no error.
