7.2.10 delete ¶

Syntax ¶

(delete [this|previous|next])

or

(take [this|previous|next])

Description ¶

Delete the indicated expression. Prefer previous and next as those are deterministic in the placement of point after the transformation, i.e., they don’t need to move point.

Examples ¶

"Swap current and previous expression."

(symex-eval
  (symex-traversal
    (do (take previous)
        (drop after))))
