DATA name TYPE seoclsname.
DATA reader TYPE REF TO /clean/reader.A variable and its type belong together and should therefore be visually grouped in close proximity.

Alignment also produces needless editing overhead, requiring you to adjust all indentations when the length of the longest variable name changes.
