Use names(.SD) in the LHS of := assignment now works!

DT[, names(.SD) := lapply(.SD, normalize), .SDcols = is.numeric]

Highly requested since 2014; turns out it was a one-line fix ✏️

fcase() supports vectors in default, making it much more flexible & matching SQL CASE WHEN ... ELSE behavior.

fcase(

type == "fruit" & full_name %in% apples,

"Apple",

type == "vegetable" & full_name %in% broccoli,

"Broccoli",

default = full_name

)

Much obliged to @davis for providing design feedback here!
