Your use case of using dynamic arrays to create a more flexible function definition would be a useful one. However I think that's more the exception than the rule. For a vendor to start supporting these type of dynamic types (within synthesis) where in the end, everything must be statical...
and are used to model and verify hardware behavior at a detailed level. The net data types also have multiple strength levels and resolution functions for multiple drivers of the net. SystemVerilog adds several new data types, which allow hardware to be modeled at...
