I think dynamic arrays are really elegant features of Pascal and a strong
benefit versus C. However, when working with large projects one encounters
situations where one wants more. control. I would advocate allowing developers
to optionally use SetLengthNoInit and also allowing user to specify
The dynamic arrays in Lazarus have so many terrific properties. Giving power
users the ability to not initialize them would give clear performance benefits.
This is useful in real world sitautions where one has long term arrays, but
also can use transient arrays of the same type. Another feature

You all make good points. It's why I didn't suggest changing SetLength
because of the well-defined and safe behaviour, and yes, the System unit
is already crowded with intrinsics, and will become even more crowded
once the naming format of the assembly intrinsics are finalised. The
