The signature of the predicate function should be equivalent to the following:

 bool pred(const Type &a);

The signature does not need to have const &, but the function must not modify the objects passed to it.
The type Type must be such that an object of type forward_list<T,Allocator>::const_iterator can be dereferenced and then implicitly converted to Type. ​
