I think it could be a new refinement, like /length
head change/lenght "abc" "def" 2
=="dec"

Now I do:
change-length: func [dest source length][
change dest copy/part source length
]
head change-length "abc" "def" 2
== "dec"
de
is copied twice and new memory allocated for it every time. (my real "de"
is 1 Mb long!)
This doesn't seem more fast:
change-length2: function [dest source length][x][
x: ""
change dest head insert/part clear x source length
]
head change-length2 "abc" "def" 2
=="dec"
