size_t[] a = [0, 1, 2, 3]; a[] += 1; // ---> implemented size_t[] b = a[] + 1; // ---> Not yet implemented --------------------- import std.stdio; void main(){ size_t[] a = [0, 1, 2, 3]; size_t[] b = a[] + 1; writeln( a ); }

The error message here is wrong, it's not that the array operation isn't implemented, it's that 'size_t[] b = a[] + 1;' is not a valid array operation, it would require allocating storage for b.

Now gives: DMD v2.065 DEBUG testx.d(4): Error: invalid array operation b = a[] + 1u (did you forget a [] ?)
