In line with the proposal in #4682, this changes the array syntax to be array(T, N). `array` is a builtin keyword which must be followed by parens containing two expressions and a separating comma. The array type expression is still fully builtin, it does not forward to a Core.Array library type yet. It merely adds the `ArrayType` instruction, as was done with the previous syntax. Followup work will change the instruction to reference to Core.Array, once the library type exists and can be used directly. --------- Co-authored-by: zygoloid <richard@metafoo.co.uk>
