The next error message is:

test.d(8,29): Error: incompatible types for ((count(alias pred = 
"a == b", Range, E)(Range haystack, E needle) if 
(isInputRange!Range && !isInfinite!Range && 
is(typeof(binaryFun!pred(haystack.front, needle)) : bool))) > 
(10)): 'void' and 'int'

So it's referring to std.algorithm.count, that probably is 
imported by one of the other two imports.
