//
// - on built-in array use: copyUp() symbol and add it to the resize-list
//
// - on user array declaration: add it to the resize-list
//
// - on block redeclaration: copyUp() symbol and add it to the resize-list
// * note, that appropriately gives an error if redeclaring a block that
// was already used and hence already copied-up
//
// - on seeing a layout declaration that sizes the array, fix everything in the
// resize-list, giving errors for mismatch
//
// - on seeing an array size declaration, give errors on mismatch between it and previous
// array-sizing declarations
