// Enhancement-102: name-then-range array-valued parameters.
//
// `parameter real c[0:2] = '{...}` (dimensions AFTER the name) now compiles,
// complementing the type-then-range form `parameter real [0:2] c`
// (Enhancement-14/15). Local variables, nets, and ports already accepted the
// name-then-range spelling (Enhancement-18/89/91); this closes the gap for
// parameters. Each name carries its own dimensions, so a multi-name declaration
// may mix widths, and multi-dimensional names are supported too.
//
// Elements are exposed as OSDI parameters `c[0]`, `c[1]`, ... exactly as for the
// type-then-range form, so per-element `.model` overrides work unchanged.
