[Lazarus] "global" operator overloading

No, it's not a dilemma, but rather a requirement. Before generics
specialization, all required operations for given type must be known. This
is because the symbol table when the generics is parsed must be
reconstructed when it gets specialized. Think about declaring usual classes
with the generic parameter replaced with actual type. If at that time, the
operation < is not yet defined, the code won't compile anyway.
