Right I'm for variadic '...$options' as proposed with indexed arguments (just like
c). Python calls this positional arguments.
I'm stretching the comparison to see if syntax could be augmented to serve another use case
(with named arguments)?
..$options[] would be more similar to **keyparam in python:
