Interesting!
Do you understand this:
7H. Formal Array Parameters. The number of dimensions for
formal array parameters must be specified in programs and shall
be determinable during translation. Determination of the
subscript range for formal array parameters may be delayed
until invocation and may vary from call to call. Subscript
ranges shall be accessible within function and procedure bodies
without being passed as explicit parameters.
Subscript ranges are not accessible in D or Rust.
I do not understand the meaning of "subscript ranges"? Isn't
this slicing?
I believe this means the range of the underlying array. For
arrays on the heap, the D runtime could actually figure this out
(using the same mechanism as for calculating .capacity), but of
course it can't be done generally.
