Implicit conversion error

".length" returns a size_t, and 0 is an int. uniform() probably 
decides to unify those types to a size_t. A size_t is 32 bit on 
32 bit machines and 64 bits on 64 bit machines. But D "int" is 
always a 32 bit signed integer. D allows implicit assignment of a 
32 bit size_t to int but not a 64 bit size_t to an int. I agree 
that it's a bit of a mess.
