crasher: --- void main() { enum v = __vector(float[4]).init; const(float)[] a = v[]; } --- > dmd: dmd/backend/cod2.d:4261: Assertion `cast(int)(*e).Eoper == 147 || cast(int)(*e).Eoper == 146' failed. Does not happen if v storage is set to `const` instead of `enum`

This is now regarded as an error, as it is slicing an rvalue.

Use .array property instead of slicing.
