struct S

string generate(S t)

}

string generate(S t)

It compiles and breaks with multiple definition of 
'_D1b8generateFS1b1SZAya' at link time. dmd v2.067

Fine. Then I expect it not to break the linking when the function 
is not called. Now it does, albeit only when -cov is used.

To see all errors you should link the code. Then you can fix them.
