AutoSized Array Bounds in Declarations

[damianmoz]

The declaration

const x = [ 1, 2, 3, 4, 5 ];

automatically deduces the upper bound of x but mandates a lower bound of 0

It would be useful if the following syntax (or something like it using a legal range) was legal:

const x : [0..] int = [ 1, 2, 3, 4, 5];

This would then allow declarations like

const x : [1..] int = [ 1, 2, 3, 4, 5];
const edge : [-1..] = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0 ];

for those of us who work with arrays that are not always 0-based, especially those who port old code from other languages.

Not urgent. Not critical. No temporary workaround needed. Thanks.
