When has anyone had a problem with unreorderable named arguments 
in functions with large argument lists?

After using languages with unreorderable and reorderable named 
parameters. I only see a very mild benefit of programmer laziness 
for reorderable, and the larger downside of reader annoyance. 
I've felt no downsides of unreorderable (you generally look at 
the documentation, and type it in param by param, or copy paste 
the declaration, and if you get it wrong, the compiler tells you 
and you fix it).
