I recall that Visual Basic has UBound function that returns upper
bound of a multi-dimensional array:
Dim a(100, 5, 4) As Byte
UBound(a, 1) -> 100
UBound(a, 2) -> 5
UBound(a, 3) -> 4
Works for single-dimensional arrays, too:
Dim b(8) As Byte
UBound(b) -> 8
I brought a point that VB has a UBound function that does exactly what
opDollar is supposed to do, so something like opUpperBound() might fit.
Finally, a viable alternative to opDollar! I could live with
opUpperBound.
<nitpick>
VB's ubound doesn't do exactly the same thing as $; in your code snippet
b(0)
b(8)
are both valid elements.
Does opUpperBound imply an opLowerBound?
In VB you can declare things like
dim a(20 to 100, 5, 1 to 4) as Byte
LBound(a,1) -> 20
Yep. Visual Basic. Awesome language. *Cough*
Lower bound is always 0 in D, unlike VB where is can take an arbitrary
value. As such, there is no need for opLowerBound in D.
Why does it make any sense that the lower bound of any arbitrary class
needs to be 0?
I'd say opUpperBound is as wrong as opEnd.
